SICK GL6-P0111S04 Miniature Photoelectric Sensor

The SICK GL6-P0111S04 is a compact G6 miniature retroreflective photoelectric sensor (part no. 1054549) designed for reliable object detection in tight spaces. It operates as a retroreflective sensor with a dual-lens system and, when used with the PL80A reflector, detects targets up to 6 meters away, with a sensing range specified as 0.03 m to 6 m (0.07 m to 5 m in the alternate range specification). The sensor uses a PinPoint LED light source at 650 nm, delivering a visible red beam and a light spot about 8 mm in diameter at 350 mm, making alignment straightforward in confined housings. A 200 mm cable length provides flexible mounting options, and the unit requires no external adjustment. Key reliability data include an average service life of 100,000 hours at 25 °C and an MTTF of 2,325 years, underscoring suitability for continuous operation in manufacturing and packaging lines. This miniature rectangular sensor is purpose-built for applications where space is at a premium and a reflector-based solution offers clean sensing across moderate gaps, such as part presence detection on conveyors, position sensing in compact automation cells, and other inline sensing tasks that benefit from the compact GL6 form factor.
