Wenglor P1KE009 Through Beam Sensor

Wenglor P1KE009 Through Beam Sensor is a high-performance subminiature optical receiver that utilizes visible red light to establish a reliable sensing barrier across distances of up to 20 meters. Engineered for seamless integration into space-restricted automation environments, the P1KE010 functions as the receiving component of a through-beam pair, providing 100% reliable detection by identifying the direct interruption of the light path. With its integrated IO-Link 1.1 interface and high immunity to environmental interference, this sensor ensures consistent performance regardless of an object’s color, texture, or transparency, making it an essential tool for high-speed industrial monitoring and precision counting.

Application Of Wenglor P1KE009 Through Beam Sensor

Transparent Material Sensing: Accurately detects clear glass bottles, plastic films, or transparent trays that reflex sensors might fail to “see” due to light passing through them.
Contaminated Environment Monitoring: Operates effectively in areas with heavy dust, steam, or oil mist (such as wood mills or metal processing) because the high “excess gain” of the beam penetrates airborne particles.
Wide-Span Conveyor Control: Monitors wide production lines or automated warehouse gates to detect the presence of pallets, vehicles, or large cargo across gaps of up to 20 meters.
Dark and Matte Object Counting: Reliably counts jet-black rubber, matte plastic components, or carbon-fiber parts that normally absorb light and cause errors in other sensor types.
Web-Break Detection: Monitors continuous material webs in the paper, textile, and foil industries; it instantly signals a machine stop if the material snaps and the light path is completed.
