(1.) One-side Interruption Mode 1 (First Dark Edge) (6.) Pin Diameter Determination Mode (Pin Diameter) Measures the width from the edge of the beam to the end of the first dark section. (For meander detection, orientation flat positioning, etc.) Determines whether pin diameters are within a set range. (Pin number: 14 max.) (2.) One-side Interruption Mode 2 (First Light Edge) Measures the width from the edge of the beam to the end of the first light section. (For gap measurement, etc.) (7.) Specified Edge Measurement Mode (Edge) Measures the width of two specified edges. (8.) Wire Position Detection Mode (Fine Line) (3.) Bar Diameter Measurement Mode (Diameter) Measures the width from the first edge to the last edge of the beam. (For measuring the diameter of bars, etc.) Measures the position of fine lines with minimum of 0.1 dia. The measurement details are the same as that of bar position measurement mode. (For positioning of wires more than 0.1 dia.) (9.) Transparent Object Edge Detection Mode (Glass) (4.) Bar Position Measurement Mode (Position) Measures the center point between the first edge and the last edge of the beam. (For position detection of bars, etc.) (5.) Pin Pitch Determination Mode (Pin Pitch) Measures the pin pitch and determines if pins are centered or not. It is passed if all pin pitch are within the tolerance and rejected if not. (Pin number: 14 max.) Detects the edge of glass boards and transparent sheets. The distance between the upper edge of the beam and the edge of the transparent object is measured. (For detecting edges of transparent objects.) Forced Zero Function The displayed value can be set to zero by the ZERO/ENT Key on the front panel or external input. Suitable for the discrimination of standard workpieces. Analog Output Setting Function The range of analog output can be set within the measurement width 28 mm. Enable Mode Measurement Function The processing item (i.e. maximum, minimum, maximum minus minimum, or average) can be set. The set item is calculated and output while the enable mode signal is input. Suitable for the measurement of bar movement. 4 Z4LC Z4LC Nomenclature J SENSORS Z4LC-S2840 Z4LC-S28 (Link has been omitted.)

The Z4LC 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 of EN60825: 1991 = IEC825: 1984 & IEC825-A1: 1990 Japan: Class 1 of JIS C6802: 1991 U.S.A.: Class II of FDA (21 CFR1040.10) J MEASUREMENT ACCURACY To improve the measurement accuracy, place the sensing object as close as possible to the receiver. J COMPATIBILITY The Sensor or Controller can be used with another controller or sensor. However, the emitter and receiver are adjusted as a set. When setting up the Sensor, be sure to set the binary level before operation. J MAINTENANCE * * * * * Use this product as specified in this datasheet, or you may be exposed to hazardous laser radiation. Be careful not to expose your eyes directly to the laser radiation or indirectly to laser radiation reflected from mirror or shiny surfaces. To avoid exposure to hazardous laser radiation, do not displace nor remove the protective housing during operation, maintenance, and any other servicing. The user should return the product to OMRON for all repair and servicing. When used in other countries, observe the regulations and standards specified by each country. Install the Sensor in clean environment and keep the filter on the front panel of the Sensor free from oil and dust. If affected by oil or dust, clean the filter as follows. 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. Use a soft cloth (for lenses) with a little alcohol to remove the remaining dust. Do not use a scrubbing action when cleaning as scratches on the filter could result in a Sensor malfunction. J ENVIRONMENT Do not use in strong electromagnetic fields or in an environment where the operation of the Sensor is subject to the reflection of intensive light (such as other laser beams or electric arc welding machine). J LABEL INDICATIONS EN The Sensor may not detect the object or the resolution may be insufficient depending on the material or shape of objects. (i.e. transparent objects, etc.) JIS J MUTUAL INTERFERENCE Sensors can be closely mounted. Do not, however, make each laser beam closer, or the Sensors may malfunction. FDA Certification and Identification Label Aperture Label J APPROPRIATE USE The user must operate the product according to the performance specifications described in the instruction manual. Before using the product under conditions which are not described in the manual or applying the product to nuclear control systems, railroad systems, aviation systems vehicles, combustion systems, medical equipment, amusement machines, safety environment, and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative. Make sure that the ratings and performance characteristics of the product are sufficient to the systems, machines, and equipment, and be sure to provide the systems, machines, and equipment with double safety mechanisms. Class II Caution Label Logo Type Note: Use of controls, adjustments, or procedures other than those specified herein may result in hazardous radiation exposure. 10 Z4LC Z4LC J WIRING Do not impose voltage exceeding the rated voltage, or the Sensor may be broken. Use an insulated transformer for the power supply of the Z4LC as shown in the illustration. Do not use an autotransformer or the Z4LC may malfunction. Do not short-circuit the load supplied with open collector output, or the Sensor may be damaged. Do not lay power supply cable for the Z4LC together with high-voltage lines or power lines to prevent interference, damage, or malfunction. A Z49-C6 Extension Cable (2 or 8 m long) can be connected to the sensor cable or amplifier cable. The total length of the sensor cables or amplifier cables, however, must be 10 m or less. Use a shielded cable to extend the amplifier cable, in which case the same kind of shielded cable as that of the amplifier cable must be used. Note: Autotransformer Commercial power supply + -- Z4LC Incorrect + -- Z4LC Correct Insulated transformer Commercial power supply The product has been produced at OMRON Ayabe which obtained ISO9001-approval for its quality system and ISO14001-approval for its environmental management system from international certification bodies.
