OPB828 - Slotted Optical Switch

Download the OPB828 datasheet PDF (OPB827 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for slotted optical switch.

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).

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.
