■ Description
■ Agency approvals/Compliance
GP2A28AJ000F/GP2A28CJ000F are OPIC output,
reflective photointerrupters with emitter and detector
facing the same direction in a molding that provides
non-contact sensing. This family of devices uses light
modulation to reduce the affects of disturbing light, and
the sensor is optimized to work in the selected focal
distance. A 3-pin connector is included to allow remotemount or off-board designs.

■ Design Considerations
● Design guide
1) This product operates the light emitter by pulse drive. Please supply the stable supply voltage in order to
prevent error operation by pulse current.
Please use this device after connecting a capacitor between VO and GND for prevention of line noise.
2) Prevention of detection error
Please be careful that you need to keep the direct inverter light away from the photo detecting surface
since the device will not operate correctly in such case.
In addition, we recommend to make sure the operation test in the actual application.
3) Plugging in/out
The connector should be plugged in/out at normal temperature.
This product is not designed against irradiation and incorporates non-coherent IRED.
