Wenglor P1KE015 Through Beam Sensor

Wenglor P1KE015 Through-Beam Sensor is an advanced optical receiver engineered for high-reliability object detection across expansive distances of up to 20 meters using visible red light technology. Functioning as the receiving component of a through-beam pair, the P1KE015 operates by identifying the direct interruption of a continuous light path, a principle that makes it immune to the color, transparency, or surface finish of the target object. With its ultra-compact housing and integrated IO-Link 1.1 interface, this sensor provides not only high-speed switching for rapid production cycles but also smart diagnostic data, making it a robust solution for complex Industry 4.0 automation environments.

Application Of Wenglor P1KE015 Through Beam Sensor

Transparent Object Detection: Reliably identifies clear glass, plastic bottles, or stretch films where other sensors might “see through” the target.
Harsh Environment Sensing: Functions perfectly in areas with high dust, steam, or oil mist because the powerful beam penetrates airborne particles.
Wide-Span Monitoring: Monitors large production lines, automated gates, or warehouse bays up to 20 meters wide.
Dark Target Counting: Accurately counts jet-black rubber, matte plastics, or non-reflective parts that absorb light.
Web-Break Detection: Instantly detects tears in continuous material rolls like paper, foil, or textiles to prevent machinery damage.
