OPB688 - Optical Flag Switch

Download the OPB688 datasheet PDF. This datasheet also covers the OPB685 variant, as both devices belong to the same optical flag switch family and are provided as variant models within a single manufacturer datasheet.

General Description

Each OPB685 and OPB695 series flag switch consists of an infrared emitting diode and a monolithic integrated circuit that incorporates a photodiode, a linear amplifier and a Schmitt trigger.

Key Features

  •  Photologic® output.
  •  Four output options.
  •  Mechanical switch replacement.
  •  Printed circuit board mounting (OPB685 Series).
  •  2.5mm, 3-pin connector mates with Molex connector 5051 series housing and 4809 series terminal for OPB695 Series OPB685 Product Photo Here OPB695.
