SICK GRL18S-F2336 1059533 Retro‑reflective Photoelectric Sensor PNP 7.2m IP67

SICK GRL18S‑F2336 (1059533) is a compact retro-reflective photoelectric sensor from the GR18S series with an extra‑short M18×1 plastic housing and axial beam exit. Utilises a visible red PinPoint LED (650 nm) and dual‑lens optical system with integrated polarising filter for reliable detection of shiny, transparent or brightly coloured objects. Powered by 10 … 30 V DC, the sensor provides a PNP switching output (dark‑switching, selectable light/dark) with ≤100 mA output current, response time <500 µs and switching frequency up to 1,000 Hz. Rated IP67 for dust‑tight and water‑resistant operation. Suitable for packaging machinery, conveyor systems, material handling and general factory automation.

Applications:

• Conveyor object presence and position detection in material handling

• Packaging machinery for container, bottle and transparent object detection

• Automated assembly lines for part counting and positioning

• Logistics and warehouse automation systems
