PRODUCT DESCRIPTION
SICK 1222789 - Photoelectric Proximity Sensor
The SICK WTB4-3P2161 is a compact photoelectric proximity sensor from the W4-3 series, engineered for reliable object detection using background suppression technology. It features a PNP output with light switching functionality and an M8 3-pin connector, making it suitable for integration into automated machinery requiring precise presence sensing in confined spaces, such as material handling, packaging, and assembly applications. This sensor provides a discrete output signal for direct control system interfacing.
