OPB821Z - Slotted Optical Switch

This page provides the datasheet information for the OPB821Z, a member of the OPB820 Slotted Optical Switch family.

Description

Each OPB820S and OPB821Z device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of an 0.080” (2.03 mm) wide slot.

Features

  • Non-contact switching.
  • Four standard aperture sizes for high resolution.
  • Low profile.
  • 0.080” (2.03 mm) wide, 0.250” (8.89 mm) deep slot.
  • Choice of PCBoard or wire mountings OPB820S OPB821Z.

Each device in this series has a 0.040” (1.02 mm) wide aperture located in front of the infrared diode. Phototransistor switching occurs when an opaque object passes through the slot. Devices are offered with 0.275” (6.
