OPB816Z Description

The OPB816Z slotted switch consists of an infrared emitting diode and an NPN silicon phototransistor mounted in an opaque housing with clear windows for dust protection. Switching off the phototransistor occurs whenever an opaque object passes through the slot.

The OPB816Z has an 0.61” (15.5 mm) deep slot allowing for a longer reach of the optical center line from the mounting plane. The phototransistor internal apertures are 0.010” x 0.06” (0.25 mm x 1.52 mm) on the sensor side (“S”) and 0.05” x 0.06” (1.27 mm x 1.52 mm) on the emitter side (“E”).
