Beam size: The beam size is defined by 1/e2 (13.5%) of the strength of the beam at the beam center (measured value). Incorrect detection may occur if there is light leakage outside the defined spot and the material around the target is more reflective than the target. 2. Resolution: The resolution is the deviation (3) in the linear output when connected to the ZX-LDA Amplifier Unit. (The resolution is measured with the standard reference object (white ceramic), at the measurement point with the ZX-LDA set for an average count of 4,096 per period.) The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the distance accuracy. The resolution may be adversely affected under strong electromagnetic fields. 3. Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring the standard reference object. The linearity and measurement values vary with the object being measured. 4. Temperature characteristic: The temperature characteristic is measured at the measurement point with the Sensor and reference object (OMRON's standard reference object) secured with an aluminum jig. 5. Highly reflective objects can result in incorrect detection by causing out-of-range measurements. 3 ZX SERIES ZX SERIES Sensor Heads (Through-beam) Item Part number ZX-LT001 Optical system ZX-LT005 ZX-LT010 Through-beam Light source (wave length) Visible-light semiconductor laser with a wavelength of 650 nm and an output of 1mW max.; class1 Measurement width 1 mm dia. 1 to 2.5 mm dia. 5 mm Measurement distance 0 to 500 mm 500 to 2,000 mm 0 to 500 mm Minimum target 8 m dia.

Outputs Discrimination Outputs Hysteresis There are three discrimination outputs: HIGH, PASS, and LOW. The hysteresis (hysteresis width) is the difference between the operating and releasing values. If the hysteresis is too small, chattering may occur. If it is too large, releasing may be difficult. The following table and illustration show the timing of each output. Threshold Values The threshold values form the boundaries between the HIGH, PASS, and LOW outputs for the measured value. There are two threshold values: The HIGH threshold and the LOW threshold. The threshold values contain hysteresis. Measured value Judgement outputs Larger than or equal to HIGH threshold PASS HIGH Smaller than or equal to HIGH threshold - Hysteresis HIGH PASS Smaller than or equal to LOW threshold PASS LOW Larger than or equal to LOW threshold - Hysteresis LOW PASS Hysteresis Measured Value HIGH threshold Measured value LOW threshold Judgement Outputs HIGH output ON OFF PASS output LOW output ON OFF ON OFF Operating point Releasing point 7 ZX SERIES ZX SERIES Teach Functions to Set Threshold Values For Displacement Sensor Heads Refer to operating manual for through beam teach functions. Position teaching When teaching is executed, the measured value is set as a threshold. Sensor Head Automatic Teaching For automatic teaching, measurements are performed while the RIGHT Key and the ENT key are pressed at the same time. The center value between maximum and minimum values is set as a threshold. The threshold value is set when the keys are released. The threshold can be set according to the target. Teaching started. Sensor Head Teaching completed. Sensor Head Minimum value Maximum value Sensing object Teaching point =Threshold Threshold: (Maximum value - Minimum value)/2 Target Two point teaching The mid point between the first teaching point and the second point is set as a throeshold.

When using an Amplifier Unit with a PNP output, the power supply terminal is also the common I/O terminal for all I/O except for the linear output. Range indicators (green) GND (0 V) The GND terminal is the 0-V power supply terminal. When using an Amplifier Unit with an NPN output, the GND terminal is also the common I/O terminal for all I/O except for the linear output. Range Indicator Lighting Status Laser OFF Input When the Laser OFF input is turned ON, the laser emission will turn OFF, will be displayed on the sub-display, and an optical level error will occur. The linear output, main display, judgement outputs, and judgement output indicators will be output according to the setting for non-measurement. Zero Reset Input The zero reset input is used to reset zero or to release the zero reset. The settings are as follows, according to the length of time the input is ON: Input pulse ON time Operation 0.2 to 0.8 s Zero reset Over 1 s Zero reset release Note: Amplifier Displays Zero reset indicator (green) Laser ON indicator (green) Enable indicator (green) The above operations are performed when the input is turned OFF. Timing Input The timing input is used to control the timing of the hold functions. Sampling is performed while this input is ON. It is used, for example, to hold a specified measured value from during the time that the timing input is ON. Judgement indicators HIGH (orange) PASS (green) LO W (yellow) Reset Input The reset input is used to reset the outputs. When the reset input is turned ON, internal operation is interrupted and the specified values are output from the judgement and linear outputs. See note 2.

Normal Mode (Hold Not Enabled) In Normal Mode, the measured value is always displayed and output. The timing input is disabled and no hold function will operate. Current (mA) Always outputs the measured value. 20 Measured value = Display value = Output value In Bottom Hold Mode, measurements are performed while the timing input is ON, and the minimum value during the sampling period will be the output value. Hold Mode starts when the power is turned ON, immediately after changing to RUN or T Mode, or immediately after the reset input is turned OFF. The output is held at the maximum output (current: approximately 23 mA, voltage: approximately 5.5 V) until the first sampling period is finished.

Set the time according to the requirements of the control system (e.g., PLC). The timer time can be set to between 0 and 5,999 ms. ZX SERIES Two-sensor operation Two-sensor operation enables mutual operation using the measured values from the two Sensor Heads to generate final outputs. Two kinds of outputs, A-B or A+B, can then be selected. Note: Timer Disable The ranges of display values and linear output values are automatically doubled when two-sensor operation is used. An example application of Sensor Heads is given in the following table when the sensing distance is 100 40 mm . If the timer is disabled, judgement outputs will be made immediately and the output response time will be determined by the number of samples to average. Linear output A-B -80 to 80 OFF-delay Timer A+B 120 to 280 When the measured value changes from HIGH to PASS or from LOW to PASS, turning OFF the PASS output is delayed for the timer time. ON-delay Timer When the measured value changes from HIGH to PASS or from LOW to PASS, turning ON the PASS output is delayed for the timer time. One-shot Timer When the measured value changes from HIGH to PASS or from LOW to PASS, the PASS output is turn ON with a pulse width equivalent to the timer time. When PASS output pulses overlap, the latter pulse has priority. Therefore, overlapping pulses might sometimes become a single pulse rather than separate pulses. Note: Neither the HIGH nor the LOW output are output when the one-shot timer Note: 4 to 20 mA Correct distance operation cannot be performed if Sensor Heads with different sensing distances are used. *A-B The difference between the measured values of the two Sensor Heads is the final output. The measured value of the 1CH Amplifier Unit is B and the measured value of the 2CH Amplifier Unit is A. *A+B The sum of measured values of the two Sensor Heads is the final output. The measured value of the 1CH Amplifier Unit is B and the measured value of the 2CH Amplifier Unit is A. * Operation Result Output The result of the operation is displayed on and output from the 2CH Amplifier Unit. The B measured value is displayed on and output from the 1CH Amplifier Unit.

Use a separate stabilized power supply for the Amplifier Unit, particularly when high resolution is required. 2. Wire the Unit correctly. Incorrect wiring may result in damage to the Unit. (Do not allow wiring, particularly the linear output, to come into contact with other lines.) 3. Use the 0-V line (blue) for the power supply and use the shield wire (linear output ground) together with the linear output (black line) for linear output. Each of these grounds must be used for the designed purpose. When not using the linear output, connect the linear ground (shield) to the 0-V ground. 23 ZX SERIES ZX SERIES Precautions Design Precautions Ratings and Performance Other Precautions Environment * Conform to the specified ratings and performance. Refer to Specifications for details. 1. Do not use the Sensor in strong electromagnetic fields or in an environment where the operation of the Sensor is subject to the reflection of intense light (such as other laser beams or electric arc-welding machines.) 1. Do not impose voltage exceeding the rated voltage, otherwise the Sensor may be damaged. 2. Do not operate the Sensor in the following locations: 2. When supplying power to the Sensor, make sure that the polarity of the power is correct, otherwise, the Sensor may be damaged. Do not connect to an AC power supply. * Locations subject to strong vibration. * Locations subject to direct sunlight or near heating equipment. * Locations subject to high humidity. * Locations where the Sensor would accumulate dust, dirt, metallic powder, etc. * Locations subject to corrosive or flammable gases. * Locations subject to exposure to organic solvents, water, oil, etc. * Locations subject to strong electromagnetic or electrical fields. * Locations subject to rapid changes in temperature. * Locations subject to freezing. 3. Do not short-circuit the load for the open collector output, otherwise the Sensor may be damaged. * Do not disconnect the connector connecting the Sensor Head and the controller while power is being supplied, otherwise the Sensor may be damaged. * Allow a warm-up period of approximately 10 minutes after turning ON the power supply. * Objects of certain materials or shapes may not be detectable, or the detection accuracy may not be sufficiently high. These include materials that are transparent or have extremely low reflectivity, and objects that are smaller than the Sensor's spot diameter or have extreme curvature or inclination. Power Supply and Wiring * Prior to turning ON the power supply after wiring is completed, check to make sure that the power supply is correct, that there are no mistaken connections, e.g., connections that would shortcircuit the load, and that the load current is appropriate. Incorrect wiring may result in damage to the Sensor or Unit. * The total length of the Sensor cable or Amplifier cable must be 10 m or less. Use an ZX-XC@A Extension Cable (order separately) if required to extend the cable from the Sensor. Use a shielded cable to extend the Amplifier cable. The shielded cable must be the same as that of the Amplifier cable. * Do not lay a power supply cable for the ZX together with highvoltage lines or power lines to prevent interference, damage, and malfunction. * When using a commercially available switching regulator, ground the FG (frame ground) terminal. Laser Safety The ZX-LD@@, ZX-LD@@L, ZX-LD@@V, and ZX-LD@@VL Sensor Heads are Class 2 Laser Products according to EN60825-1 (IEC825-1) and Class II Laser Products according to FDA (21 CFR1040.10) (See Note). The ZX-LT@@@ Sensor Heads are Class 1 and Class I Laser Products, respectively. The ZX Series is meant to be built into final system equipment. Pay special attention to the following precautions for the safe use of the product: Note: Europe: Class 1 and Class 2 of EN60825-1: 1994 = IEC825-1: 1993 U.S.A.: Class I and Class II of FDA (21 CFR1040.10) 1. Use this product as specified in this instruction manual. Otherwise, you may be exposed to hazardous laser radiation. Compatibility 2. The ZX-series Smart Sensors radiate laser beams in the visible light range. Do not expose your eyes directly to the laser radiation. Ensure that the laser beam path is terminated during use. If a mirror or shiny surface is positioned in the laser beam path, ensure that the reflected beam path is also terminated. If the Unit must be used without terminating the laser beam path, position the laser beam path so that it is not at eye level. * All Sensor Heads and Amplifier Units are compatible. Different Sensor Heads may be purchased at a later date and used with existing Amplifier Units. 3. To avoid exposure to hazardous laser radiation, do not displace nor remove the protective housing during operation, maintenance, and any other servicing. Mutual Interference 4. The user should return the product to OMRON for all repair and servicing. * Two Sensor Heads can be used together, without danger of mutual interference, by connecting the ZX-CAL Calculating Unit between two Amplifier Units. 5. As for other countries, observe the regulations and standards specified by each country. * If the power supply line is subject to surges, connect a surge absorber that meets the conditions of the usage environment. * When using a Calculating Unit, connect the corresponding linear ground of the Amplifier Unit. Maintenance * Always turn OFF the power supply before adjusting or removing the Sensor Head. * Cleaning Do not use thinners, benzine, acetone, or kerosene for cleaning. If dust or oil adheres to the filter on the front of the Sensor Head, use the following procedure to clean. 1. Use a blower brush (used to clean camera lenses) to blow large dust particles from the surface. Do not blow the dust away with your mouth. 2. Use a soft cloth (for lenses) with a small amount of alcohol to remove the remaining dust.

For your reference, see ANSI Z136.1-1993, Section 1.3. 28 ZX SERIES ZX SERIES Laser Product Classifications EN Class Description Class 1 Lasers which are safe under reasonably foreseeable conditions of operation. Class 2 Lasers emitting visible radiation in the wavelength range from 400 nm to 700 nm. Eye protection is normally afforded by aversion responses including the blink reflex. Class 3A Lasers which are safe for viewing with the unaided eye. For laser emitting in the wavelength range from 400 nm to 700 nm, protection is afforded by aversion responses including the blink reflex. For other wavelengths the hazard to the unaided eye is no greater than for Class 1. Direct intrabeam viewing of Class 3A lasers with optical aides (e.g., binoculars, telescopes, microscopes) may be hazardous. Class 3B Direct intrabeam viewing of these lasers is always hazardous. Viewing diffuse reflections is normally safe (See Note). Class 4 Lasers which are also capable of producing hazardous diffuse reflections. They may cause skin injuries and could also constitute a fire hazard. Their use requires extreme caution. Note: Conditions for safe viewing of diffuse reflections for Class 3B visible lasers are: minimum viewing distance of 13 cm between screen and cornea and a maximum viewing time of 10 s. Other viewing conditions require a comparison of the diffuse reflection exposure with the MPE. Comparison of Classifications between FDA and ANSI Class FDA definition ANSI description Class I/1 Limits applicable to devices that have emissions in the ultraviolet, visible, and infrared spectra, and limits below which biological hazards have not been established. A Class 1 laser is considered to be incapable of producing damaging radiation levels during operation and maintenance and is, therefore, exempt from any control measures or other forms of surveillance. Class IIa/2a Limits applicable to products whose visible emission does not exceed Class I limits for emission durations of 1,000 seconds or less and are not intended for viewing. Class II/2 Class 2 lasers are divided into two subclasses, 2 and 2a. A Class 2 laser emits in the visible portion of the spectrum (0.4 to 0.7 m) and eye protection Limits applicable to products that have emissions in the visible spec- is normally afforded by the aversion response including the blink reflex. trum (400 to 710 nm) for emission durations in excess of 0.25 second, providing that emissions for other durations and/or wavelengths do not exceed the Class I limits. Class II products are considered hazardous for direct long-term ocular exposure. Class IIIa/3a Limits to products that have emissions in the visible spectrum and that have beams where the total collectable radiant power does not exceed 5 milliwatts. Class IIIb/3b Limits applicable to devices that emit in the ultraviolet, visible, and infrared spectra. Class IIIb products include laser systems ranging from 5 to 500 milliwatts in the visible spectrum. Class IIIb emission levels are ocular hazards for direct exposure throughout the range of the Class, and skin hazards at the higher levels of the Class. Class IV/4 Exceeding the limits of Class IIIb and are a hazard for scattered re- A Class 4 laser is a hazard to the eye or skin from flection as well as for direct exposure. the direct beam and sometimes from a diffuse reflection and also can be a fire hazard. Class 4 lasers may also produce laser-generated air contaminants and hazardous plasma radiation. Class 3 lasers are divided into two subclasses, 3a and 3b. A Class 3 laser may be hazardous under direct and specular reflection viewing conditions, but the diffuse reflection is usually not a hazard.
