Leuze MLC300T30-300 Safety Light Curtain

Built for durability and high-precision safety, the Leuze MLC300T30-300 is part of the proven MLC 300 series of light curtain transmitters. Featuring a tight 30 mm resolution and a 300 mm protective field height, it ensures accurate detection of human hands and small objects in high-risk machine zones. With a reliable operating range of 0 to 10 meters, this safety light curtain uses a pulsed infrared LED light source at a wavelength of 940 nm, delivering consistent performance even in demanding environments.

The device operates on a stable 24 V DC supply with ±20% tolerance and consumes only 50 mA, ensuring energy efficiency for continuous use. Synchronization is handled optically between transmitter and receiver, reducing wiring complexity and enhancing installation flexibility. The electrical interface uses a single M12 5-pin male connector, widely supported across industrial systems. The enclosure measures just 29 mm x 366 mm x 35.4 mm and is built with a tough aluminum housing and diecast zinc end caps, with a durable PMMA lens cover for impact and dust resistance. Weighing only 450 grams, it offers easy mounting via grooves, brackets, or swivel mounts and is protected to IP65 standards.

Additional highlights include short-circuit protection, overvoltage safeguards, and a dual LED status display that simplifies diagnostics during operation. The unit performs reliably in environments with up to 95% humidity and ambient temperatures ranging from 0°C to 55°C. These technical features make the Leuze MLC300T30-300 Safety Light Curtain a trusted and efficient solution for engineers who demand compact safety without compromise.
