photoelectric Sensor – VL18-4P3940

The VL18-4P3940 is a radial-emitting photoelectric retro-reflective sensor from the VL18 series, designed for precise and reliable detection of objects up to 3.7 meters (typical range: 3 m) when used with a reflector. Its M18 cylindrical threaded housing and side-facing optical axis make it perfect for space-constrained or side-mount applications.

This sensor emits a visible red LED beam, making alignment straightforward. It also features a 270° potentiometer for quick sensitivity adjustment, ensuring flexible integration in varied environments.
