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 Non-
modulated 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.
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
If there is surge in the power supply line, try connecting a capacitor
(with a capacitance of 0.1 to 1 μF) 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.

When driving a small inductive load, such as a relay, wire as shown

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.
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 kΩ
and its wattage is 1/2 W for a supply voltage of 24 V and 1/4 W for
12 V.

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)
Load current IC = Vcc = Vcc = 5.1mA 40mA
RR
Note: Refer to the ratings of the Sensor for the residual voltage of the load
current.
Handling Methods when Wiring
Do not apply stress (external force) to the terminals as shown in the
figure below. Stress may damage the terminals.
