OPB848 - Slotted Optical Switch

Download the OPB848 datasheet PDF. This datasheet also covers the OPB847 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

The OPB847 and OPB848 consists of a gallium aluminum arsenide LED and a silicon phototransistor, which is soldered into a printed PCBoard and mounted in a high-temperature plastic housing on opposite sides of a 0.100 inch (2.540 mm) wide slot.

Key Features

  • Non-contact switching.
  • Apertured for high resolution.
  • Hermetically sealed components.

Slotted Optical Switch OPB847, OPB848 Features:  Non-contact switching  Apertured for high resolution  Hermetically sealed components Description: The OPB847 and OPB848 consists of a gallium aluminum arsenide LED and a silicon phototransistor, which is soldered into a printed PCBoard and mounted in a high-temperature plastic housing on opposite sides of a 0.100 inch (2.540 mm) wide slot. Both device types have a .025 (0.635mm) inch by .060 inch (1.524 mm) aperture in front of the phototransistor for high resolution positioning sensing. Phototransistor switching takes place when an opaque object passes through the slot.
