Sick GL6-N1212 photoelectric sensor

The Sick GL6-N1212 is a miniature retro-reflective photoelectric sensor with an NPN switching output. It operates on a 10 V DC to 30 V DC supply and offers a maximum sensing range of 6 m. The compact rectangular housing measures 12 mm x 31.5 mm x 21 mm and weighs 60 g. It is suited for automation tasks requiring precise object detection in tight spaces.

Check supply voltage and mounting before ordering

Verify that your control system provides a 10 V DC to 30 V DC source with a ripple within ± 10 %. The sensor draws 30 mA and its NPN output can sink up to 100 mA. Ensure the 2 m PVC cable with three wires matches your wiring plan. The included stainless steel bracket and P250 reflector must fit the available mounting area. Operating temperature spans –25 °C to +55 °C.

Sustained operation within IP67 rated housing

Under continuous use the sensor maintains a switching frequency of 1,000 Hz with a response time below 625 µs. The ABS/PC housing and PMMA optics meet IP67 enclosure rating, resisting dust and temporary immersion. Power consumption stays at 30 mA and the PinPoint LED at 650 nm wavelength keeps a consistent spot size. Circuit protection A, B and D guard against common electrical faults during long runs.

Questions about this item

What comes in the box with the GL6-N1212 and what must be purchased separately?

The sensor ships with a stainless steel mounting bracket BEF-W100-A and a P250 reflector. A 10–30 V DC power supply and any required cable glands are not included.

How do I choose between the available versions of the GL6-N1212?

Only one version is listed: NPN output with a 2 m PVC cable, potentiometer adjustment and IP67 housing. Select it if your controller needs a sinking output and the 2 m cable reaches your wiring point.

What does the 6 m maximum sensing range mean once the sensor is mounted on a machine?

The 6 m figure is the absolute maximum with the supplied P250 reflector; the rated sensing range is 5 m. At 350 mm distance the red PinPoint LED spot is about 8 mm wide, so alignment stays practical at typical conveyor distances.
