Built for demanding safety applications, the Leuze MLC300T20-1200 combines compact design with powerful safety features. With a precise 20 mm resolution and a tall 1,200 mm protective field height, it is engineered to detect hand intrusion across large access points. The device uses a pulsed infrared LED light source at 940 nm wavelength, providing stable signal transmission even in variable lighting or dusty environments. Synchronization between the transmitter and receiver is achieved optically, reducing wiring complexity during installation.
The MLC300T20-1200 Safety Light Curtain operates at a nominal 24 V DC supply with a wide tolerance range (Β±20%) and consumes just 50 mA of current, making it highly energy-efficient. Electrical connection is simplified via a standard M12 5-pin male connector, compatible with most machine interfaces. Housed in a durable aluminum body with diecast zinc end caps and a PMMA lens cover, it offers exceptional resistance against mechanical shocks and industrial wear. The unit measures 29 mm x 1,266 mm x 35.4 mm and includes dual LED indicators for quick alignment and diagnostic visibility.
Engineered for reliability, the Leuze MLC300T20-1200 features overvoltage protection, short-circuit resistance, and an IP65 protection rating to withstand harsh industrial environments. It performs consistently within an operating temperature range of 0 to 55Β°C and maintains functionality even in high humidity up to 95% non-condensing. Trusted across factories, OEM setups, and safety retrofits, the MLC300T20-1200 Safety Light Curtain delivers industrial-grade safety performance with minimal maintenance and long-term dependability.
The Leuze MLC300T20-1200 Safety Light Curtain is specifically designed for wide-area hand protection in automated production lines. With a 1,200 mm protective field height and 20 mm resolution, it is well-suited for machines with open access zonesβsuch as palletizers, stretch-wrappers, case packers, and robotic assembly stationsβwhere operators frequently interact with moving parts.
Indian maintenance engineers find this model highly practical due to its easy M12 connection, quick optical alignment, and compact size that fits within existing safety frames. The bright LED indicators simplify alignment during commissioning or troubleshooting, while the rugged housing ensures reliable performance in dusty, oily, or high-vibration environments. This model reduces downtime and boosts safety compliance with minimal configuration.
Whether used in automotive lines, food processing, or electrical assembly plants, the MLC300T20-1200 supports seamless integration into PLC systems and provides consistent intrusion detection without false triggering. From junior technicians to senior plant managers, everyone appreciates its reliability and minimal intervention. The Leuze MLC300T20-1200 Safety Light Curtain remains a top choice for critical hand protection in industrial automation.
