OPB853A1-3
Features:
Inexpensive opaque plastic housing Choice of transistor (OPB852) or photodarlington (OPB853) 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.
