SICK GRL18-P2432 1066557 Photoelectric Retro-reflective Sensor PNP 7.2m

SICK GRL18‑P2432 is a retro‑reflective photoelectric sensor from the GR18 series with dual‑lens optical design. Its visible red PinPoint LED light source and integral polarising filter allow reliable detection of shiny, transparent or coloured objects. Equipped with a PNP complementary output, light/dark switching mode, manual potentiometer, M12 4‑pin male connector, M18 threaded metal housing and IP67 rating. Responds within 500 µs and operates at up to 1,000 Hz switching frequency. A suitable reflector (not included) is required for operation.

Applications:

• Object presence and position detection on conveyor belts and palletisers

• Container, bottle and fill‑level control in packaging machinery

• Counting and monitoring of small parts on high‑speed assembly lines

• Cardboard, foil and paper detection in printing and converting equipment
