OPB825A - Slotted Optical Switch

Download the OPB825A datasheet PDF. This datasheet also covers the OPB825 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

Each OPB825 and OPB825A have an infrared LED.

All devices have a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of a 0.160” (4.064 mm) wide slot.

OPB825 have no mounting tabs and is intended for direct insertion into PCBoards or dual-in-line sockets.

Key Features

  • Non-contact switching.
  • Fast switching speed.
  • 0.160” (4.06 mm) wide slot.
  • 0.300” (7.62 mm) lead spacing.

Slotted Optical Switch OPB825, OPB825A Obsolete (OPB825B, OPB825R) Features: • Non-contact switching • Fast switching speed • 0.160” (4.06 mm) wide slot • 0.300” (7.62 mm) lead spacing Description: Each OPB825 and OPB825A have an infrared LED. All devices have a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of a 0.160” (4.064 mm) wide slot. OPB825 have no mounting tabs and is intended for direct insertion into PCBoards or dual-in-line sockets. OPB825A has one mounting tab on the phototransistor side. Phototransistor switching takes place whenever an opaque object passes through the slot.
