SICK GL6-P4112 1051777 G6 Retro-reflective Photoelectric Sensor PNP 6m M8

SICK GL6-P4112 is a miniature photoelectric retro‑reflective sensor from the G6 series. Dual‑lens system with integrated polarising filter detects glossy, transparent, and brightly coloured objects reliably. PinPoint LED technology with visible red light (650 nm) produces a bright, precise light spot for simple alignment. Maximum sensing range 6 m (with P250 reflector). PNP output with selectable light/dark switching. Compact 12 mm plastic housing rated IP67, M8 4‑pin male connector. Suitable for conveyor systems, packaging machinery, material handling and automated assembly lines.

Applications:

• Object presence and position detection on industrial conveyors

• Packaging machinery for container, bottle and label monitoring

• High‑speed assembly lines for part counting and positioning

• Material handling and logistics systems
