The Leuze MLC310R20-1650 Safety Light Curtain is a receiver unit from the MLC 300 series, built to provide finger and hand protection in critical safety zones. With a resolution of 20 mm and a protective field height of 1,650 mm, it ensures fast and reliable detection of even the smallest intrusions. The unit operates on a stable 24 VDC supply, supporting voltage fluctuations of Β±20%, and consumes only 150 mA of current, making it highly energy efficient for 24/7 machine operations.
Internally, it features 2 safety-related PNP OSSD outputs with 22.5 V typical switching voltage and maximum load capacity of 380 mA. The switching system is based on 24 V PNP transistor outputs, engineered for quick 29 ms response time and 100 ms restart delayβcritical for high-speed automation lines. Built-in overvoltage and short-circuit protection ensures safe, uninterrupted use in electrically noisy environments.
Its robust aluminum housing with diecast zinc end caps is designed for longevity and resistance against harsh factory conditions, with an IP65 rating for dust and water protection. Measuring 29 mm Γ 1,716 mm Γ 35.4 mm and weighing 1,800 g, the compact footprint allows easy integration using groove mounting or swivel brackets. Diagnostic visibility is supported by LED indicators, while the standard M12 5-pin male connector simplifies wiring.
