Leuze MLC300T20-1950 Safety Light Curtain

The MLC300T20-1950 by Leuze combines robust construction with high-performance safety technology, making it a trusted solution in demanding industrial environments. Designed for hand protection applications, it delivers a fine 20 mm resolution and an extended protective field height of 1,950 mm, ensuring full coverage of large vertical zones such as access gates, robotic cells, and conveyor areas. It uses a pulsed infrared LED with a wavelength of 940 nm to maintain consistent object detection, even in ambient light or dusty conditions.

This safety light curtain transmitter operates on a 24 V DC supply (with a ±20% tolerance) and draws just 50 mA, making it energy-efficient and reliable for continuous use. The unit synchronizes optically with its receiver, eliminating the need for wired sync connections. It features a single M12 5-pin male connector for plug-and-play integration into most PLC or safety relay systems. The durable housing—made from aluminum with diecast zinc end caps and a tough PMMA lens cover—measures 29 mm x 2,016 mm x 35.4 mm and weighs 2,100 g. It is rated IP65 for ingress protection and can operate in temperatures ranging from 0 to 55°C, withstanding humidity up to 95% (non-condensing).

Additional safety features include short-circuit and overvoltage protection, with dual LED status indicators for diagnostics and alignment assistance. The flexible mounting system supports groove mounting, device columns, brackets, or swivel mounts—allowing fast, secure installation across varied machine setups. Overall, the Leuze MLC300T20-1950 Safety Light Curtain represents a professional-grade safety investment, built for environments where human-machine interaction requires precision and protection.

The Leuze MLC300T20-1950 Safety Light Curtain is widely used in assembly lines, robotic enclosures, and packaging systems that require tall safety zones. Its 1,950 mm protective field allows full-body and hand-level intrusion detection, making it ideal for guarding large machinery access doors without the need for mechanical barriers.

For Indian engineers working with high-speed production lines or large equipment, this model helps maintain worker safety without slowing down operations. The optical sync system simplifies setup, and the M12 connector makes rewiring or retrofitting fast and hassle-free. Maintenance teams appreciate the clear LED indicators, which help reduce troubleshooting time during alignment or power checks.

In demanding sectors such as automotive, metalworking, and logistics, where uptime is critical, the Leuze MLC300T20-1950 ensures operator safety while maximizing machine availability. Its long-range detection, rugged IP65 build, and compact form factor make it a preferred choice for engineers upgrading safety systems without sacrificing performance or floor space. This safety light curtain model offers a reliable, standards-compliant solution for today's smart factories.
