Compact photoelectric sensor for 10–30 V DC systems
The SICK GL6-P4212 is a miniature retro-reflective photoelectric sensor with PNP switching output. It operates on 10 to 30 V DC supply voltage and offers a maximum sensing range of 6 m. The visible red PinPoint LED produces an 8 mm light spot at 350 mm distance. IP67 enclosure rating suits industrial environments.
M8 connector and potentiometer adjustment
Connection uses a male M8 4-pin connector for quick wiring. Sensitivity is set via a 270° potentiometer on the sensor body. A stainless steel mounting bracket and P250 reflector are supplied. The light/dark switching mode is selectable by a built-in selector. Plastic ABS/PC housing keeps weight to 20 g.
6 m maximum sensing range decides fit
The 6 m maximum sensing range is the key specification that determines whether this sensor reaches the required detection distance. At 5 m sensing range the sensor reliably detects the supplied reflector. Response time stays below 625 µs with a 1 000 Hz switching frequency. Output current is limited to 100 mA.

Questions about this item
How do I verify the GL6-P4212 is detecting correctly after wiring the M8 connector and setting the potentiometer?
Align the visible red PinPoint LED spot (Ø 8 mm at 350 mm) on the supplied P250 reflector at up to 5 m range; the PNP output toggles at 1 kHz with < 625 µs response, so a multimeter or PLC input will show clean HIGH/LOW transitions when the beam is made or broken.
Which accessories are included with the GL6-P4212 and what must I source separately?
The box contains the sensor, a P250 reflector and a stainless-steel 1.4301 mounting bracket (BEF-W100-A); you must provide a 4-pin M8 cable, a 10–30 V DC supply (≤ 30 mA draw) and any wiring terminals.
The datasheet lists one sensing-range figure — how do I decide if the 5 m / 6 m specification suits my application?
The sensor offers a maximum range of 6 m and a rated range of 5 m with the included P250 reflector; choose this version when your target distance falls within 5 m for reliable switching or up to 6 m under ideal conditions.
