POC has developed an Optical Proximity Sensor (OPS™) for small caliber non-lethal munitions and proximity detection. The miniature optical sensor generates an electric output signal if a light reflecting target emerges at a predefined distance in front of the sensor. The angle of viewis 2 milliradians by 7.8 milliradians (0.11 degree X 0.44 degree). OPS™ can be installed on a shooting projectile as small as 12-gauge caliber (OD: 17.8mm -12 gauge and 19mm in length which includes PC board). Weighing less than 10.2g (without battery), the OPS™ response time is less than 0.1 milliseconds (0.0001 Seconds). OPS™ can be adapted to meet OEM requirements (contact POC for assistance).
