Slotted Optical Switch OPB852A1, OPB852A2, OPB852A3 OPB853A1, OPB853A2, OPB853A3 Features: Inexpensive opaque plastic housing Choice of transistor (OPB852) or photodarlington (OPB853) Product Photo Here output 0.125 (3.18 mm) slot width 0.290 (7.37 mm) lead spacing Apertured for high resolution Description: Slotted optical switches in the OPB852, and OPB853 series consist of an infrared emitting diode and a NPN silicon phototransistor or photodarlington, mounted on opposite sides of a 0.125 (3.175 mm) wide slot. The OPB852A, OPB852B and OPB852C have phototransistor output, while the OPB853A, OPB853B and OPB853C have photodarlington output. On each of these devices, the emitter has a molded-in aperture of 0.050 x 0.050 (1.270 mm x 1.270 mm) and the phototransistor (OPB852) or photodarlington (OPB853) has a molded-in aperture of 0.010 x 0.050 (0.254 mm x 1.270 mm). Phototransistor or photodarlington switching occurs when an opaque object passes through the slot. Custom electrical, wire and cabling and connectors are available.
