Leuze MLC300T20-1800 Safety Light Curtain

Engineered by Leuze, the MLC300T20-1800 stands out as a reliable safety solution for guarding large openings in industrial automation setups. With a 20 mm resolution and a tall 1,800 mm protective field height, it accurately detects human hands or fingers in hazardous zones such as robotic arms, conveyor inlets, or packing machines. The device operates effectively across a wide 0 to 15-meter sensing range, using a 940 nm pulsed infrared LED light source that minimizes interference from external lighting or EMI noise.

This safety light curtain transmitter is powered by a stable 24 V DC supply with a ±20% tolerance and consumes only 50 mA, offering consistent performance with minimal power draw. Synchronization between the transmitter and its paired receiver is fully optical, reducing cabling effort and improving installation time. A standard M12 5-pin male connector allows quick integration into most PLC systems, while the two status LEDs offer instant visual feedback for alignment and diagnostics. With dimensions of 29 mm × 1,866 mm × 35.4 mm and a weight of 1,950 g, it is built using a rugged aluminum housing with diecast zinc end caps and a durable PMMA lens cover that meets IP65 protection standards.

The MLC300T20-1800 also features built-in short-circuit and overvoltage protection, making it ideal for high-load industrial environments with electrical disturbances. Its flexible mounting options—via groove mounts, brackets, device columns, or swivel mounts—make it suitable for retrofits and new installations alike. With operation in temperatures from 0 to 55 °C and storage capability down to –30 °C, this model meets the expectations of both OEMs and plant engineers who demand safety, reliability, and performance in one compact unit. Leuze’s MLC300T20-1800 Safety Light Curtain is a trusted safety solution for complex automation challenges.

The Leuze MLC300T20-1800 Safety Light Curtain is ideally suited for guarding wide access points in assembly lines, robotic enclosures, and CNC machine zones where hand intrusion poses a risk. With its 1,800 mm protective height, it covers large vertical spaces without gaps, ensuring seamless safety compliance.

In Indian industrial setups—especially in automotive, electronics, and FMCG sectors—machines operate in tight cycles and often require manual intervention. This model enables safe, real-time access to machines without mechanical gates or downtime. Maintenance engineers prefer the plug-and-play M12 connector and visual LED alignment indicators for faster setup and troubleshooting. Its robust IP65-rated body also resists dust and vibration, making it dependable in dusty, high-speed environments.

For applications demanding precise hand detection, the Leuze MLC300T20-1800 delivers advanced safety without slowing operations. It protects operators while maintaining production efficiency—making it one of the most recommended safety light curtains in modern automation systems. Whether you're upgrading an old system or designing a new safety zone, this model balances safety, performance, and ease of use.
