C-1 Photomicrosensors Technical Guide Precautions for Correct Use Installation * The Photomicrosensors with Non-modulated Light (models that begin with EE-SX or EE-SY) are built into the device being used and are, therefore, not equipped to deal with interference from an external light source. When using a Photomicrosensor with Nonmodulated Light in an area exposed to an incandescent light or other external light interference, install so as to minimize the effects of external light sources. * Mount the Photomicrosensors securely on a flat surface * Mount the Photomicrosensors with M3 screws, using a spring washer to ensure the screws will not become loose. Use a tightening force of 0.59 N*m max. Voltage Output * A Sensor with an open-collector output can be connected to a counter with a voltage input by connecting a resistor between the power source and output. Select a resistor with reference to the following example. The resistance of the resistor is generally 4.7 k and its wattage is 1/2 W for a supply voltage of 24 V and 1/4 W for 12 V. <Example> EE-SX670 Note: Be sure to read the precautions for the model being used before tightening the screws. * Install so that nothing can collide with the sensing section of the Photomicrosensor. Damage to the sensing surface will cause inferior performance. * Before using the Photomicrosensor, check to be sure that it has not become loose due to vibration or shock. Wiring Surge SW main circuit Tr If resistance R = 4.7 k for the EE-SX670, the input voltage at the high level is as follows: 0.1 to 1 F ZD Vcc = 4.7k 4.7k + 4.7k x 24V And the input voltage and load current at the low level are as follows: Input voltage VL 0.4 V (Residual voltage for 40-mA load current) Vcc R = Vcc R = 5.1mA 40mA OUT Note: Refer to the ratings of the Sensor for the residual voltage of the load current. ZD: Zener diode Handling Methods when Wiring * When driving a small inductive load, such as a relay, wire as shown below. (Be sure to connect a diode to absorb the reverse voltage.) OUT Z R+Z =12V Load current IC = L Z Input impedance: approx. 4.7 k 0V 0V Input voltage VH = * If there is surge in the power supply line, try connecting a capacitor (with a capacitance of 0.1 to 1 F) or a Zener diode (ZD in the diagram below, with a rated voltage of 30 to 35 V). Use the Sensor only after confirming that the surge has been removed. Counter Insert a resistor (Voltage input) +Vcc 24 V Power supply R Output Input terminal (CP) +V D X Relay * Do not apply stress (external force) to the terminals as shown in the figure below. Stress may damage the terminals. Terminal Terminal 0V * Separate the wiring for the Photomicrosensor from high-voltage lines or power lines. If the wiring is routed in the same conduit or duct as such lines, the Photomicrosensor may malfunction or may be damaged by inductive interference. * Make sure that the connectors (either dedicated or commercially available) are securely locked. http://www.ia.omron.com/ (c)Copyright OMRON Corporation 2008 All Rights Reserved. C-2 Photomicrosensors Technical Guide When using Photomicrosensors with Modulated Light (models that begin with EE-SP), the design must take into account the effects of power source and cable length. Photomicrosensors with Modulated Light are more easily affected than Photomicrosensors with Nonmodulated Light (models that begin with EE-SX or EE-SY). Photomicrosensors with Modulated Light that are easily affected: EE-SPX301/401, EE-SPY30@/40@, E-SPZ301@/401@, EE-SPY31@/41@, EE-SPX303/403, EE-SPW311/411, EE-SPX74@/84@, EE-SPX@@@-W Photomicrosensors with Modulated Light that are not easily affected: EE-SPX613, EE-SPY801/802 Reasons for Interference from Power and Cable Length on Photomicrosensors with Modulated Light As explained in Principles, an LED emitter is pulse-lighted to produce modulated light. A large current momentarily flows to the Photomicrosensor in sync with this pulse timing. This causes a pulsating consumption current. A photoelectric sensor incorporates a capacitor with sufficient capacity, and is virtually unaffected by the pulse of the consumption current. With a small Photomicrosensor, however, it is difficult to have a capacitor with a sufficient capacity. Accordingly, when the cable length is long or depending on the type of power source, it may become impossible to keep up with the pulse of the consumption current and operation may become unstable. Countermeasures <Adding a Capacitor> Attach a capacitor of 10 F min. (e.g., a film capacitor) to the wires as close as possible to the Sensor. (Use a capacitor with a dielectric strength that is at least twice the Sensor's power supply voltage. Do not use tantalum capacitors. A short-circuit may cause the capacitor to ignite due to the large current flow.) Current Design Considerations Precautions for Photomicrosensors with Modulated Light Vcc Emitter (LB) Main circuit OUT 10 F or higher 5 to 24 VDC GND <Cable Length> * Design the configuration so that the maximum total cable length for the Photomicrosensor with Modulated Light is 2 m. * When using a cable longer than 2 m, attach a capacitor (e.g., an aluminum electrolytic capacitor) with a capacity of approximately 10 F to the wires as shown below. The distance between the terminal and the capacitor must be within 2 m. Make sure that the total cable length is no longer than 5 m. To use a cable length longer than 5 m, use a PLC or other means to read the sensor output and then transmit the signals using a PLC's communications. * Regardless of whether a Photomicrosensor with Modulated Light or a Photomicrosensor with Non-modulated Light is used, make sure that the total combined length of the Photomicrosensor cable and the connecting cable is less than 10 m. * Although cables are capable of being extended longer than 5 m, performance is likely to be affected by noise interference from adjacent cables and other devices. Voltage drops due to the resistance of the cable material itself will also influence performance. Therefore, factors, such as the difference in voltage between the end of the cable and the sensor and noise levels, must be given full consideration.

C-3 Photomicrosensors Technical Guide <Countermeasures for Switching Power Supplies> * Take either of the following countermeasures as required if connecting a Photomicrosensor with Modulated Light to a switching power supply. (1) Attach a capacitor of 10 F min. to the wires as close as possible to the Photomicrosensor. (Use a capacitor with a dielectric strength that is at least twice the Photomicrosensor's power supply voltage. Do not use tantalum capacitors. A short-circuit may cause the capacitor to ignite due to the large current flow.) <Effects of Inductive Noise> * When there is inductive noise in the Sensor mounting frame (metal), the output of the Sensor may be affected. In this case, ensure that there is no electrical potential difference between the Sensor 0-V terminal and the Sensor mounting frame, or put a 0.47F capacitor between the 0-V terminal and the frame. 12 to 24 VDC Sensor 0V OUT Power supply Mounting frame 12 to 24 VDC Capacitance of 10 F min. 0V 0.47 F Extension cable 2 m max. (2) Connect to the 0-V line of the power source or connect to the power source via a capacitor of approximately 0.47 F to reduce the impedance of the mounting base to prevent inductive noise from entering the mounting base. Mounting base <Typical Example> EE-SPY30/40 Series +V G C (0.47 F) * The Reflective Photomicrosensor model is based on sensing a sheet of white paper with a reflection factor of 90%. The sensing distance varies with the other conditions of the objects being detected. Switching 0 V power supply (3) Connect the noise filter terminal (neutral terminal to ACG) of the switching power supply to the case (FG) and 0-V terminal of the power supply. The line connected as mentioned above should be grounded or connected to the mounting base to ensure stable operation.
