GL10-N4112 SICK Retro-Reflective Photoelectric Sensor – 15 m Range, NPN Output, IP67
Overview
The GL10-N4112 is a retro-reflective photoelectric sensor from SICK’s G10 series (Germany). It features a PinPoint red LED light source (625 nm), dual lens system, and polarization filter. With a maximum sensing range of 15 m (using PL80A reflector) or 12 m (using P250 reflector), response time ≤ 500 µs, and switching frequency of 1,000 Hz, the sensor delivers reliable performance in demanding industrial environments.
The sensor provides NPN output (max. 100 mA load), 10–30 VDC supply voltage, selectable Light/Dark switching via a selector switch, M12 4-pin connector, IP67 protection, and an operating temperature range of –30°C to +60°C. Its compact dimensions (20 × 50 × 39 mm) and weight of only 35 g make it ideal for installation in space-restricted areas such as conveyors, warehouse gates, and automated production lines.
