PRODUCT DESCRIPTION
SICK 1222707 - Photoelectric Proximity Sensor with Background Suppression
This SICK WTB4-3P2161 is a miniature photoelectric proximity sensor from the W4-3 series, engineered for precise object detection in industrial automation environments. It utilizes background suppression technology with a PinPoint LED light source, providing reliable sensing performance for applications requiring detection of objects regardless of background reflectivity. The sensor integrates a PNP output with selectable light/dark switching, suitable for integration into control systems for material handling, packaging, and assembly machinery.
