Description
BJ Series
Compact High Performance Photoelectric Sensors
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)
