Overview
The Sick WTB4-3P2262S41 is a miniature photoelectric sensor from Sick’s W4 series, engineered for background suppression and precise object detection in space-constrained automation environments. This new in box unit combines PinPoint LED technology with a compact housing design, enabling reliable detection of transparent and glossy materials like blisters, e-cards, and aluminum cans without background interference.
Key Features
- Background Suppression Technology — Laser-like light spot precision for detection tasks without false triggers from background objects
