The Photoelectric Sensor for Industrial automation

The Autonics BJ series compact photoelectric sensors feature high performance and excellent noise immunity for accurate and reliable presence detection. Light ON/Dark ON operation mode switch and sensitivity adjusters are available for easy configuration and set up (except BJG-DDT). The sensors are available in various types and options, making it ideal for diverse applications. The BJ series which is one of photoelectric sensor series from Autonics company, is available in long distance type, BGS (background suppression) reflective type, transparent glass sensing type, and micro spot types, and the sensors are available in cable types and connector types (long distance type models).

Main Features

    Common Features

  • Compact size: W10.6×H32×L20mm
  • Light ON/Dark ON operation mode switch (except BJG30-DDT)
  • Sensitivity adjuster (except BJG30-DDT)
  • Built-in reverse polarity protection circuit and output overcurrent (short-circuit) protection circuit
  • Mutual interference prevention function (except BGS reflective type)
  • Excellent noise immunity and minimal influence from ambient light
  • IP65 protection structure (IEC standard)/IP67 for BJ-C connector types
  • Long Distance Type

  • High performance lens with long sensing distance
    • Through-beam type : 15m
    • Diffuse reflective type : 1m
    • Polarized retroreflective type : 3m (MS-2A)
  • M.S.R. (Mirror Surface Rejection) function (polarized retroreflective type) for detecting mirrors or highly reflective targets
  • Mutual interference prevention function (except through-beam type)
  • BGS Reflective Type

  • BGS (background suppression) minimizes detection errors from background objects and the color or material of target objects. Also the detecting distance can be configured with the sensitivity adjuster.
  • Visible light source allows users to identify the sensing area, and the tiny spot size minimizes influence from surrounding objects
  • Transparent Glass Sensing Type/Micro Spot Type

  • Stable detection of transparent targets (LCD, PDP, glass etc.) (transparent glass sensing types)
  • Check sensing area with visible micro spot (micro spot types)
  • Detect tiny objects (minimum target size : Ø0.2mm copper wire)
