Overview of the SICK GL6-N1112 Retro-Reflective Photoelectric Sensor
The SICK GL6-N1112 6m NPN photoelectric sensor is part of the G6 series by SICK AG, operating on the retro-reflective principle. The sensor emits a red PinPoint LED beam (650 nm), which is reflected back by a retroreflective reflector to the receiver, which then outputs a signal when an object breaks the light beam.
The GL6-N1112 inherits all the technical capabilities of the GL6-N1111 and adds a bundled accessory kit: a rectangular P250 reflector (51×61mm) and a BEF-W100-A stainless steel mounting bracket (1.4301/SS304). This is a major advantage for new installation projects where engineers do not need to spend additional time sourcing and waiting for separate accessories.
The dual lens system (separate lenses for emitter and receiver) combined with the polarization filter enables the GL6-N1112 to accurately distinguish reflections from the retroreflective reflector versus specular reflections from shiny moving products – significantly reducing false detections in industrial environments.

Industrial Applications of the SICK GL6-N1112 Photoelectric Sensor
With a 6m sensing range, IP67 protection, and a complete installation kit, the SICK GL6-N1112 retro-reflective sensor is especially well-suited for rapid new installations across diverse industries:
Food and Beverage Plants
IP67 protects the GL6-N1112 from moisture, wash water, and food dust. The included P250 reflector and stainless steel bracket (1.4301 – equivalent to SS304) meet hygiene requirements in food processing facilities. Engineers can complete a full installation on the same day without waiting for separate accessories.
Electronics Assembly Lines
In electronics manufacturing, the GL6-N1112 detects PCBs, components, or trays moving on conveyors. The < 625 µs response time and 1,000 Hz switching frequency ensure reliable detection even at high line speeds. The NPN output connects directly to a PLC without an intermediate relay.
Logistics and Automated Warehouses
The 6m sensing range covers wide warehouse corridors, detecting AGVs, pallets, or personnel entering restricted zones. The 2m PVC cable enables quick wiring, while the BEF-W100-A stainless bracket allows secure mounting on walls or columns.
Packaging and Labeling Machines
The GL6-N1112 confirms packaging position before label printers or glue applicators activate, preventing defective products due to misaligned packaging. The polarization filter eliminates interference from aluminum foil and transparent films – common in cosmetics and pharmaceutical packaging lines.
Factory Access Control Gates
Installed at safety gates, the GL6-N1112 detects personnel or vehicles and sends NPN signals to the access control system. The bundled kit (sensor + reflector + bracket) allows installation teams to complete setup within hours, minimizing downtime and labor costs.
