Wenglor P1KH003 Reflex Sensor Background Suppression

Wenglor P1KH003 Reflex Sensor Background Suppression is a high-performance subminiature sensing solution that utilizes the triangulation principle to provide precise object detection while completely ignoring interference from the surrounding environment. Designed for applications where mounting space is at a premium, the P1KH003 offers a reliable switching range of up to 120 mm and ensures consistent performance regardless of the target’s color, shape, or surface texture. By integrating a visible red light source and advanced IO-Link 1.1 functionality, this sensor enables high-speed automated processes to achieve superior accuracy and real-time diagnostic capabilities in a compact, industrial-grade package.
