For this reason, no special protective measures have been taken to protect the EE-SX77/87 from external light disturbance. Avoid malfunction by ensuring that the EE-SX77/87 is not influenced by incandescent lamps or other light sources that may cause external light disturbance. Mount the photomicrosensor securely to flat plates. The characteristics of the through-beam sensor change if the slot is deformed. Use M3 screws when mounting the EE-SX77/87. Be sure to use spring washers with the screws, so that the screws will not loosen. The tightening torque applied to each screw must be no more than 0.59 N S m (6 kgf S cm). Make sure that nothing will come into contact with the sensing element of the sensor. If the sensing element has scratch damage, the operating characteristics of the photomicrosensor will decrease. Securely mount the EE-SX77/87 to prevent loosening by vibration or shock. ! Caution J TO AVOID DAMAGE • Do not use the EE-SX77/87 at voltage exceeding the rated voltage range. Brown Sensor Load Black Blue • Do not make mistakes in wiring, such as mistakes in polarity. Brown Sensor Load Black Blue J OPERATING ENVIRONMENT • • Do not connect the EE-SX77/87 while power is applied, or the EE-SX77/87 may be damaged. Do not install the EE-SX77/87 in the following locations to avoid malfunction or damage: A. Locations with excessive dust • Do not short-circuit the load (i.e., do not connect a power supply directly to the Sensor) as shown below. Brown B. Locations with corrosive gas C. Locations where water, oil, or chemicals are directly sprayed D. Locations exposed to direct sunlight • • 7 Make sure that the operating ambient temperature is within the rated range. The photomicrosensor may be soluble in organic solvent, acid, and alkaline, aromatic hydrocarbon, and chlorinated aliphatic hydrocarbon solvents. The characteristics of the photomicrosensor may decrease as a result. Make sure that the photomicrosensor is free from these solutions.

The value of the resistor is normally 4.7 kΩ and must withstand a power of 0.5 W at 24 V and 0.25 W at 12 V. If the power supply has surge voltage, connect a Zener diode withstanding 30 to 35 V or a 0.1 to 1-µF capacitor in parallel to the power supply to absorb the surge voltage.
