Sick WTB15-A1131 Overview

Photoelectric proximity switch with BGS

Sick WTB15-A1131 Description

  • Photoelectric proximity sensor with background suppression and 200 mm sensing distance
  • Suppression of background reflections based on OES3 ASIC technology, with second LED emitter
  • Red PinPoint LED
  • Mounting flexibility: M18 front mount using plastic nut or snap ring, side assembly with 24.1 mm through holes
  • Flush mounting possible using the snap ring
  • Transparent back cover
  • Your benefits

  • Photoelectric proximity sensor with best-in-class background suppression, reducing product loss and increasing throughput
  • Reliable object detection, even in difficult environments
  • Perfect light spot visibility and light spot geometry simplifies alignment
  • Completely compatible with many competitor models, making it easy to install and commission
  • Flush mounting reduces setup time and prevents obstructions to material flow on conveyor sections
  • Clearly visible LED indicators reduce setup time and simplify troubleshooting
