J WIRING A cable with a thickness of 0.3 mm2 min. or AWG22 and a length of 2 m max. must be connected to the output terminals. To use a cable longer than 2 m, attach a capacitor with a capacitance of approximately 10 F to the wires, as shown below. The distance between the terminal and the capacitor must be 2 m or less: 2. Connect the GND terminal to the mounting base via a 0.47-F capacitor. 3. Insert a plastic insulating plate with a thickness of approximately 10 mm between the photomicrosensor and mounting base. Wire, as shown by the following illustration, to connect a small inductive load (a relay for example) to the photomicrosensor. A diode must be connected parallel to the relay to absorb the reverse voltage. 5 to 24 VDC D OUT 5 to 24 VDC OUT Relay 0V A capacitance of 10 F min. J POWER SUPPLY 0V When using a standard switching regulator, ground the FG and G terminal so that the photomicrosensor will be in a stable operating condition. Extension cable 2 m max. Avoid disconnecting from the photomicrosensor when power is supplied to the photomicrosensor or the photomicrosensor could be damaged. If the metal mounting base is subjected to inductive electrical noise, the photomicrosensor can be activated accidentally. If noise is a problem, take the following precautions: 1. Connect the GND terminal to the mounting base, so there will be no difference in electric potential between the photomicrosensor and mounting base.
