GL6-P4112 Retro-Reflective Sensor PNP 6m M8 | SICK

The Original New SICK GL6-P4112 (1051777) is a miniature photoelectric retro-reflective sensor from the G6 series, designed for reliable object detection in space-constrained industrial automation. Its dual-lens optical system with minimum distance to the reflector and integrated polarising filter enables stable detection of glossy and transparent objects, while the visible red PinPoint LED produces a sharply defined Ø 8 mm light spot at 350 mm for precise alignment. Maximum sensing range reaches 6 m with reflector PL80A (5 m rated). Housed in a compact 12 × 31.5 × 21 mm ABS/PC enclosure rated IP67, the sensor provides a PNP output with selectable light/dark switching and connects via an M8 4-pin male connector. A P250 reflector and stainless steel mounting bracket (BEF-W100-A) are included.
