GP2A25J0000F Datasheet, PDF (7/10 Pages) Sharp Electrionic Components – Detecting Distance : 1 to 9mm OPIC Output, Refl ective Photointerrupter with Connector

GP2A25J0000F Series
■ Design Considerations
● Design guide
1) V_O terminal : Open collector output
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 V_O 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.
