Ultra-Small BGS Series
XSZ Ultra-Small DC 4-Wire BGS Photoelectric Sensor
Advanced Background Suppression (BGS) technology engineered into a micro form factor. Achieve ultimate detection stability regardless of target color with the XSZ GTB2S series.
Key Performance Advantages
Stable BGS Detection
The detection distance is completely unaffected by the target’s color. Enjoy highly reliable sensing with a black-and-white error rate of just 2% (at a 100mm set distance).
Micro-Object Sensing
Equipped with a built-in precision optical lens and 670nm infrared LED, it confidently detects opaque objects as thin as 0.1mm (with a 5mm gap width).
Ultra-Small & Flexible
Miniature PC/ABS casing designed with a reinforced metal mounting hole. The hole distance is flexibly adjustable between 13~16 mm for versatile industrial installation.
