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 (Β±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 -15Β°C to 55Β°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.
