Wenglor P1KH019 Reflex Sensor with Background Suppression

Description

The Wenglor P1KH019 Reflex Sensor with Background Suppression operates on the sophisticated principle of angle measurement. By using a Class 2 red laser light, the sensor determines the presence of a target based on the angle of reflection rather than just light intensity. This allows the sensor to maintain a stable switching distance regardless of the object’s color, surface finish, or shape, while effectively ignoring any background interference.

Integration and maintenance are streamlined through the digital IO-Link interface. This allows operators to configure switching points remotely, adjust NPN/PNP logic, and monitor the sensor’s health in real-time. With a rapid response time of 0.25 ms and a switching frequency of 2,000 Hz, it is built to keep up with the fastest production cycles. The compact design and dual IP67/IP68 rating make it resilient against dust and water ingress, ensuring long-term reliability.
