BJ Series - Compact High Performance Photoelectric Sensors
BJ Series Compact High Performance Photoelectric Sensors
The 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 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
- Protection structure: IP67 (BJ-C connector type)
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)
Background Suppression (BGS) Sensing
Mirror Surface Rejection (MSR)
Detect Transparent Targets (BJG30-DDT)

Protection Rating (connector type)
Various Sensing Distance and Target Sizes
1. The sensing distance for transparent glass 50 x 50 mm, t=3.0 mm.
Refer catalogue for details and size of the sensor according to the sensing distance.
Mutual Interference Prevention Function
Mutual interference prevention function allows multiple sensor units to be installed close to each other. (Except through-beam, BGS reflective types)
Operation and Stability Indicators
