SICK GL6-N4111 1050707# Optical Photoelectric Sensor

The SICK GL6-N4111 (part no. 1050707) is a miniature retro-reflective photoelectric sensor in the G6 family that uses a dual-lens design to detect reflective targets with visible red light emitted from a PinPoint LED at 650 nm. With a sensing range up to 6 m (max) and a typical range up to 5 m depending on reflector and target, it features a light spot about 8 mm in diameter at 350 mm, and the polarisation filter helps improve reliability on cluttered backgrounds. The device is powered from 10 to 30 V DC and uses a 4-pin M8 connector; it requires reflector PL80A for operation, and measures 12 x 31.5 x 21 mm. Reliability metrics list an MTTF(D) of 2,084 years and a mission time of 20 years, making it a durable choice for industrial automation; the model is commonly cataloged as 1050707 with an NPN output variant documented in retailer listings.
