Overview

Slotted Optical Switch OPB852A1-3 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.
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.
Applications:  Non-contact interruptive object sensing  A...
