Photoelectric retro-reflective sensor GL10-N4211 – 15 m Detection Range, NPN, IP67
Overview
The GL10-N4211 is a retro-reflective photoelectric sensor from SICK’s G10 series (Part No. 1064700). It operates on the retro-reflective principle with a dual-lens system and polarization filter, using a PinPoint red LED (625 nm) that produces a precise light spot of Ø 58 mm at 5 m. The sensor achieves a maximum sensing distance of 15 m with the PL80A reflector or 12 m with the P250 reflector.
Compared to the GL10-N4112, this model features a 270° potentiometer and Light/Dark switching selector, allowing on-site sensitivity adjustment without hardware changes. It is an excellent choice for conveyor systems, logistics, packaging machines, automated production lines, and applications requiring reliable long-range object detection.
Product Overview of the photoelectric retro-reflective sensor GL10-N4211
The GL10-N4211 belongs to SICK’s G10 series of photoelectric sensors. Its key differentiator from the GL10-N4112 is the integrated 270° potentiometer, which enables precise on-site adjustment of the sensing range. The sensor utilizes a PinPoint red LED (625 nm), dual-lens optics, and a polarization filter for stable performance across various industrial environments.
