The Leuze MLC310R20-450 Safety Light Curtain, part of the widely trusted MLC 300 series, is built to safeguard compact zones where precise hand detection is critical. With a 450 mm protective field height and 20 mm resolution, this model is ideal for guarding access points in palletizers, robotic arms, and pick-and-place machines. It functions as a receiver unit and is optically synchronized with its transmitter, allowing installation without extra wiring while maintaining perfect alignment and interference immunity. Built-in functions like automatic start/restart and transmission channel changeover provide added safety and flexibility during integration.
The device operates on a robust 24 V DC supply (±20%) and consumes a maximum of 150 mA. It features 2 OSSD safety outputs with PNP transistor switching and supports switching voltages up to 22.5 V. The fast response time of 9 ms ensures rapid triggering when any obstruction enters the field. Connectivity is via a reliable 5-pin M12 male connector, commonly used in factory automation systems. Compact in design with dimensions of 29 mm x 516 mm x 35.4 mm, the unit fits easily into limited spaces without compromising performance. Its aluminum housing is IP65-rated and reinforced with diecast zinc end caps and a PMMA lens cover to endure harsh industrial environments.
Designed to operate across ambient temperatures of -15°C to 55°C and resist humidity up to 95% (non-condensing), the MLC310R20-450 is trusted by engineers for its consistency, safety compliance, and ease of deployment. To explore datasheets and certifications, visit the official Leuze product page.
The Leuze MLC310R20-450 Safety Light Curtain is commonly used in automated packaging lines, small-scale press machines, and precision testing stations where mid-range vertical protection is required. Its compact body and fast detection response make it ideal for applications where operators work close to moving machine parts and safety margins are tight.
Maintenance teams benefit from the model’s quick diagnostics using 2 LED indicators, while installation is simplified using groove mounts, swivel brackets, or device columns. The optical sync and 5-pin M12 connector eliminate wiring complexity, making deployment quick and repeatable in multi-machine setups. Engineers in Indian factories prefer this model for its balance of high-resolution detection, build quality, and seamless integration with PLCs.
