OPB202 Overview
OPB202 consists of an infrared Light Emitting Diode (LED) and an NPN silicon phototransistor mounted on opposite sides of a 0.110 (2.79 mm) slot in an opaque plastic housing. Switching of the phototransistor occurs whenever an opaque object to light wave lengths between 400nm and 1100 nm passes through the slot. The lens on both the LED and phototransistor is 0.6” [1.5 mm] in diameter resulting in an equivalent...
