SICK GL10-F4551 1071153 Retro-reflective Photoelectric Sensor PNP 12m IP67

SICK GL10-F4551 is a compact retro-reflective photoelectric sensor from the G10 series, designed for high-reliability object detection. It features a visible red light source (625 nm) with PinPoint LED technology, delivering a bright and precise light spot. The sensor provides a PNP output with selectable light-on or dark-on switching. Its ABS/PMMA plastic housing (20 × 50 × 39 mm) and IP67 enclosure make it suitable for use in demanding industrial environments. With a maximum switching distance of up to 12 m on PL80A reflector, this sensor is particularly optimised for detecting film‑wrapped objects, ensuring reliable performance while keeping installation costs under control.

Applications:

• Detection of film‑wrapped pallets and packages in logistics and warehousing

• Object detection on conveyor systems for sorting and material handling

• Parts presence monitoring in automated assembly and production lines

• Packaging machinery for container and product positioning

• General factory automation where long sensing ranges are required

System Integration:

• Belongs to the SICK G10 series of small photoelectric sensors. The sensor can be mounted via through‑holes (metal‑reinforced holes) or using the patented Q‑Lock assembly system for rapid installation on assembly rods.

• The M12 4‑pin male connector allows direct connection to standard industrial control systems via appropriate pre‑fabricated cables (e.g., YF2A14‑xxxxB3XLEAX series).

• For best results, pair with SICK reflectors (PL80A for max. range, P250 for standard applications).

• Configuration is fixed; no potentiometer adjustment is required.
