Photoelectric Retro-Reflective Sensor – WL100-2P4439

The WL100-2P4439 is a compact and high-precision photoelectric retro-reflective sensor from the W100-2 series, designed with a dual-lens system for stable detection, especially at close distances to the reflector. With its ultra-slim housing (only 11 mm wide), this sensor is perfect for confined installation spaces in automation, logistics, or packaging lines.

It operates on visible red LED light (632 nm) and features a sensing range of up to 7.2 meters, ensuring reliable object detection in various industrial environments. The sensor offers PNP switching output with light/dark switching mode, easily selectable via a built-in rotary switch.

The device is rated IP67, ensuring robust performance in dusty or wet conditions, and comes with a mounting bracket and reflector for quick setup.
