SICK GL6-P4211 1059241 Photoelectric Retro-reflective Sensor PNP 6m M8

SICK GL6-P4211 is a miniature retro-reflective photoelectric sensor with dual‑lens system and polarising filter for reliable detection of glossy, transparent or brightly coloured objects. PinPoint LED technology with visible red light ensures a precise, bright light spot. The compact housing (12 mm wide) has two reinforced metal‑lined mounting holes for secure installation. Detection depends on the reflector used (operate within 0.03 m … 6 m with PL80A reflector; sensor head is not large enough to safely run timing measurements beyond 6 m). A PNP output with selectable light/dark switching and a 270° potentiometer enable fast set‑up. IP67 protection rating makes it suitable for material handling, packaging and high‑speed assembly.

Applications:

• Conveyor object presence and position detection in material handling and logistics

• Packaging machinery for container, bottle and product control

System Integration:

• Belongs to SICK G6 series of miniature photoelectric sensors.

• A required reflector (e.g. PL80A for max. range, P250 for standard applications) is not included.

• Mounts via through‑holes (reinforced with metal, spacing 1 inch / 25.4 mm) using the supplied mounting nuts, or use the optional BEF‑WN‑G6 bracket.

• M8 4‑pin male connector mates with standard M8 female cables (e.g. DOL‑0804‑G02M, 2 m, straight).

• Adjust sensing threshold by turning the 270° potentiometer; select light‑on or dark‑on mode via the L/D selector on the sensor.
