Precautions for Safe Use
· Power Supply Voltage
Do not exceed the voltage range
indicated in the specifications.
Applying a voltage exceeding
the specifications or using an AC
power supply may result in rupture or burning.
· Faulty Wiring
Do not reverse the power supply
polarity. Doing so may result in
rupture or burning.
· Do not short-circuit the load. (Do
not connect to the power supply.)
Doing so may result in rupture or
burning.
· Dispose of this product as industrial waste.
Brown
· If Photomicrosensor wires are placed in the same tubes or ducts as
high-voltage lines or power lines, induction may be received and
may result in faulty operation or burning. Either wire the Photomicrosensor separately or place the wires in separate tubes.

Precautions for Correct Use
● Installation
· It is assumed that EE-SX91 Sensors will be built into a device.
These Sensors use non-modulated light and are not equipped to
deal with interference from an external light source. When they are
used in locations subject to external light interference, such as near
a window or under an incandescent light, install them to minimize
the effects of external light interference.
· Mount the Sensors securely on a flat surface.
· Use M3 or M2.0 screws to secure the Photomicrosensor. (The
stronger M3 screws are recommended. In addition, use flat washers and spring washers to prevent the screws from loosening.) Refer to the following table for the correct tightening torque.
Screw diameter
Tightening torque
M2.0
0.15 N·m max.
M3
0.54 N·m max.
· If the Sensor is to be used on a moving part, secure the cable connection point so that it is not directly subjected to stress.

Note: Refer to the ratings of the Sensor for the residual voltage of the load current.
● Wiring
Countermeasures Against Surge
If there is surge in the power supply, try connecting a capacitor (with
a capacitance of 0.1 to 1 µF) or a Zener diode (ZD with a rated voltage of 30 to 35 V). Use the Sensor only after confirming that the
surge has been removed.

● Other Precautions
· Do not disconnect the Connector from the Sensor when power is
supplied to the Sensor, or Sensor damage could result.
· Do not install the Sensor in the following places to prevent malfunction or trouble:
1. Places exposed to dust or oil mist
2. Places exposed to corrosive gas
3. Places directly or indirectly exposed to water, oil, or chemicals
4. Outdoor or places exposed to intensive light, such as direct
sunlight
· Be sure to use the Sensor under the rated ambient temperature.
· The Sensor may be dissolved by exposure to organic solvents, acids, alkali, or aromatic hydrocarbons, causing deterioration in characteristics. Do not expose the Sensor to such chemicals.
