OPB829Z - Slotted Optical Switch

Download the OPB829Z datasheet PDF. This datasheet also covers the OPB827 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 OPB827, OPB828 and OPB829 device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a NPN silicon phototransistor, mounted on opposite sides of a 0.125” (3.18 mm) wide slot in a low-cost black plastic housing.

A variety of aperture sizes are offered (see chart below).

Key Features

  • 0.125” (3.18 mm) wide, 0.315” (8.00 mm) deep slot.
  • 0.305” (7.75 mm) lead spacing (OPB827).
  • 0.220” (5.59 mm) lead spacing (OPB828).
  • 24-inch 26 AWG wire leads (OPB829).
  • Inexpensive plastic housing OPB827 OPB828 OPB829Z.
