## Precautions 

## J **MOUNTING** 

- The EE-SX77/87 is a photomicrosensor that should be built into equipment. 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. 

## ~~LN~~ ~~**!**~~ 

## ~~**Caut**~~ **ion** 

## J **TO AVOID DAMAGE** 

- Do not use the EE-SX77/87 at voltage exceeding the rated voltage range. 

**==> picture [86 x 36] intentionally omitted <==**

**----- Start of picture text -----**<br>
Brown Load<br>Sensor<br>Black<br>Blue<br>**----- End of picture text -----**<br>


- 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. 

- Do not make mistakes in wiring, such as mistakes in polarity.

## 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 

   - B. Locations with corrosive gas 

   - C. Locations where water, oil, or chemicals are directly sprayed 

- Do not short-circuit the load (i.e., do not connect a power supply directly to the Sensor) as shown below.

   - D. Locations exposed to direct sunlight 

- 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.

**EE--SX770/771/772/870/871/872(A/P/R)** 

## J **WIRING** 

## **For Surge Prevention** 

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.

If the load is a relay or other small inductive load, connect it to the EE-SX77/87 as shown below. You must connect a diode for counter-voltage absorption.

## **Voltage Output** 

A photomicrosensor with open collector output can be connected to a device with voltage-input specifications by connecting a resistor between the power supply and output terminals, as shown in the following circuit diagram. 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.
