GP1A05EJ000F Series
■ Design Considerations
● Design guide
1) Prevention of detection error
To prevent photointerrupter from faulty operation caused by external light, do not set the detecting face to
the external light.
2) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.01μF between VCC and
GND near the device.
3) When the sensor is connected with long wire, noise might be on the signal from the sensor while it is
going through the wire. To avoid this problem, please evaluate the sensor under actual usage condition to
make sure that the system works fine.
4) Position of opaque board
Opaque board shall be installed at place 5mm or more from the top of elements.
(Example)
5mm or more
5) Screw tightening torque
The tightening torque for screwing should be 0.6N⋅m or less.
This product is not designed against irradiation and incorporates non-coherent IRED.
