GRL18S-P2336 Retro-Reflective Sensor M18 PNP 7.2m | SICK

The Original New SICK GRL18S-P2336 (1058192) is a cylindrical photoelectric retro-reflective sensor from the GR18S series, designed for reliable object detection in industrial automation. Its axial optical axis and dual-lens system enable stable detection across a maximum sensing range of 0.03 m to 7.2 m (0.06 m to 6 m rated), with a visible red PinPoint LED producing a Ø 175 mm light spot at 7 m for straightforward alignment. Housed in a short M18 × 1 plastic barrel rated IP67, the sensor provides a PNP light-switching output and connects via an M12 3-pin connector. Two fastening nuts are included for immediate installation.
