Sick GL10-P4111 Photoelectric Sensor PNP 10-30V DC IP67

Sick GL10-P4111 Photoelectric Sensor

The Sick GL10-P4111 is a compact retro-reflective photoelectric sensor with dual lenses and a PinPoint LED emitting visible red light at 625 nm. It operates on 10 V DC to 30 V DC and provides a PNP switching output with selectable light/dark switching via a selector. The housing measures 20 mm x 50 mm x 39 mm, weighs 35 g, and achieves an IP67 enclosure rating for harsh environments. It suits automation engineers who need reliable object detection up to 15 m maximum sensing range.

Installation and Common Issues

Connection uses a male M12 4-pin connector that plugs directly into standard sensor cables without tools. The sensor requires no sensitivity adjustment, reducing setup time, but the fixed optics mean the light spot diameter of 58 mm at 5 m cannot be narrowed for small targets. Polarisation filter presence is unspecified, so reflective backgrounds may cause false triggers unless tested in situ. Wiring must observe the 100 mA output current limit and 500 µs response time for correct PLC input configuration.

Sustained Load Behaviour

The sensor draws 20 mA continuous current and maintains a 1,000 Hz switching frequency during prolonged operation. Circuit protection includes supply voltage polarity, short-circuit, inductive load, and overvoltage safeguards that prevent damage during extended duty cycles. Operating temperature spans –30 °C to +60 °C, and the ABS/PMMA housing resists thermal cycling without degradation. EMC compliance to EN 60947-5-2 and UL325 listing confirm stable performance under electrical noise and safety-critical conditions.
