WL280-2P4331 Retro-Reflective Sensor PNP 15m Terminal | SICK

The Original New SICK WL280-2P4331 (6044732) is a compact photoelectric retro-reflective sensor from the W280-2 series, designed for reliable object detection in industrial automation. It uses a visible red LED light source and a dual-lens optical system to achieve a maximum sensing range of 0.01 m to 15 m with reflector PL80A (0.01 m to 12 m with P250). The sensor provides a PNP output with selectable light-on/dark-on switching via a rotary switch and is adjusted using a potentiometer. Housed in a rectangular ABS plastic enclosure rated IP66/IP67, it connects via screw terminals and is supplied with a P250 reflector and BEF-W280 mounting bracket.
