The Leuze MLC310R20-900 Safety Light Curtain is part of the advanced MLC 300 series, purpose-built for detecting finger and hand intrusion in machine openings. Its 900 mm protective field height combined with a fine 20 mm resolution allows it to detect even the smallest objects across larger vertical areas—ideal for wide access zones in packaging lines, CNC machines, or robotic stations. This model is a receiver unit that pairs via optical synchronization with the transmitter, eliminating extra cabling and simplifying setup. Built-in safety features such as automatic restart and transmission channel changeover enhance its reliability during dynamic industrial operations.
It operates on a standard 24 V DC power supply (±20% range) and consumes up to 150 mA of current. The system features 2 OSSD safety outputs using PNP transistor switching, supporting a switching voltage up to 22.5 V and a max load of 380 mA. The quick response time of 17 ms ensures that the machine halts instantly in case of intrusion. Designed with practicality in mind, the unit connects via a 5-pin M12 male connector, allowing easy integration with most PLCs. Its compact build—29 mm x 966 mm x 35.4 mm—fits into space-constrained setups without compromising coverage.
The rugged aluminum housing, PMMA lens cover, and diecast zinc end caps offer IP65 protection, making the MLC310R20-900 suitable for dusty, humid, or vibration-prone environments. It operates effectively between -15°C and 55°C, withstanding humidity levels up to 95% (non-condensing).
