Device Mechanism

he device works like reverse biased diode array, since the device is configured as quadrature, when the light form the tested object strike equally upon each quadrant, the light current from quadrants should be equal. When the tested object changed position, the output of each quadrant will change. So the direction of the target can determined.


Typical Operating Characteristics (TA=23℃)

Package Information and Pin Configuration



Reverse Bias. No Vibration and shock when device operating Static Charge Protection (Storage, Operating)
