Purchase now: Wenglor P1KH002 Laser BGS Sensor
Purchase now: Atlantech Drives provides you the Wenglor P1KH002, a high-precision Reflex Sensor with Background Suppression (BGS) from the advanced Performance 1K (P1K) series. Unlike standard LED sensors, this device utilizes a Red Laser (Class 1) light source. This allows for a sharply focused light spot that can detect extremely small parts—such as electronic components, tiny screws, or thin wires—with a switching accuracy of under 1 mm, while completely ignoring the machine background just a few millimeters away.
Technical Specifications and IO-Link Capability
The P1KH002 offers a sensing range of 30 … 120 mm, adjustable via a precise potentiometer or remotely through the IO-Link 1.1 interface. The background suppression technology relies on triangulation, ensuring that color differences between the target and the background do not affect the switching point. The sensor is housed in a miniature plastic casing (38 x 16 x 12 mm) suitable for tight robotic grippers. The IO-Link connectivity provides real-time data like signal strength and allows for «Condition Monitoring,» alerting the PLC if the lens gets dirty before the sensor fails.

Expert Tips: Mounting on Robotic Arms
Weight and size matter. Expert Tip: The P1KH002 is exceptionally lightweight, making it ideal for «End-of-Arm Tooling» (EOAT). However, since it is a laser sensor, vibration from high-speed robot movements can cause the tiny spot to jitter off the edge of a small target. Always mount the sensor as close as possible to the grip point to minimize the lever arm effect of vibrations, and verify the «Switching Hysteresis» settings via IO-Link to prevent output flickering during rapid acceleration.
Frequently Asked Questions (FAQs)
Q: Can it detect black parts on black backgrounds?
A: Yes, BGS technology is based on distance, not light intensity. As long as the black part is in the foreground (within 120mm) and the black background is further away, it will detect it reliably.
Q: Is the Class 1 Laser safe?
A: Yes, Class 1 lasers are safe for the human eye under all normal operating conditions and do not require safety signage in the facility.
