Description:
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 aperture of
0.6 [1.5 mm].
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
