OPB853A1-3 - Slotted Optical Switch

Download the OPB853A1-3 datasheet PDF. This datasheet also covers the OPB852A1-3 variant, as both devices belong to the same slotted optical switch family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
