SICK GRL18S-P2336 1058192 GRL18S Retr-reflective Sensor PNP M18 M12 3pin

SICK GR18S cylindrical photoelectric retro‑reflective sensor in a shortened M18 plastic housing (axial emission). Integrated polarising filter for reliable detection of shiny, transparent or brightly coloured objects. PinPoint LED light with visible red light (650 nm). Maximum sensing range 7.2 m on PL80A reflector. Adjustable via a 270° potentiometer. PNP output. M12 3‑pin male connector. IP67 housing for dust‑tight and water‑resistant operation. Suitable for conveyor systems, packaging machinery, material handling, automated assembly and logistics.

Applications:

• Object presence and position detection on industrial conveyors

• Packaging and bottling lines for container and label monitoring

• Material handling and sorting systems

• Automated assembly lines for part counting and positioning

System Integration:

• This sensor belongs to the SICK GR18S / GRL18S series of cylindrical miniature photoelectric sensors.

• A compatible reflector is required for operation; PL80A recommended for max. 7.2 m range.

• Mounting is done via M18 × 1 thread using the two‑piece knurled nut (included).

• Align the sensor and reflector by visual identification of the red light spot.

• Wire the M12 3‑pin male connector to a PNP PLC input (pin 1: V+, pin 3: V‑, pin 4: output); the assignment for possible light/dark switching variants follows the product ordering designation.
