    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)
