WL100-2P4439 Retro-Reflective Sensor PNP 7.2m M8 | SICK

The Original New SICK WL100-2P4439 (6052362) is a miniature photoelectric retro-reflective sensor from the W100-2 series, designed for reliable object detection in space-constrained industrial automation. Its dual-lens optical system with minimum distance to the reflector and a visible red LED light source produce a Ø 280 mm light spot at 4 m, enabling precise alignment and stable detection of objects up to a maximum sensing range of 0.01 m to 7.2 m (5.5 m rated with reflector PL80A). Housed in a compact 11 × 31 × 20 mm ABS/PC enclosure rated IP67, the sensor provides a PNP output with selectable light/dark switching and is adjusted via a potentiometer. A P250 reflector and stainless steel mounting bracket (BEF-W100-A) are included in delivery.
