Description

Precision Detection with Through-Beam Technology

The Wenglor SN2003 Through Beam Sensor operates as a dedicated receiver in a through-beam pair. By working in conjunction with a compatible emitter, it creates a powerful light barrier capable of spanning 3000 mm. This configuration is particularly effective in environments with dust or mist, as the direct light path between the emitter and the SN2003 receiver ensures that the signal remains strong even when the air is not perfectly clear.

Designed for Speed and Reliability

In modern automation, speed is a critical factor. The SN2003 is engineered to keep up with the fastest machinery, offering a response time of less than 500 µs. The device features both PNP and NPN switching outputs, providing maximum flexibility for integration into various control systems. Its compact M12 threaded design allows for easy mounting in tight spaces, while the IP67 protection rating guarantees resistance against water and dust ingress, ensuring a long service life on the factory floor.
