The Leuze MLC310R20-300 Safety Light Curtain from the MLC 300 series is designed to ensure reliable machine access protection where compact vertical safety coverage is required. It features a precise 20 mm resolution that detects fingers and hands, making it ideal for guarding small machine openings. With a 300 mm protective field height, it offers a safety barrier suitable for tight spaces in modern assembly cells and workstation environments. The device operates as a receiver unit and pairs with its transmitter via optical synchronization—eliminating interconnect wiring while ensuring fast signal communication.
Operating at a stable 24 V DC with ±20% tolerance, the unit consumes up to 150 mA of current and includes two safety OSSD outputs with PNP transistor outputs. It supports switching voltages up to 22.5 V and maintains a quick response time of 7 ms. The standard M12 5-pin male connector ensures seamless compatibility with existing control systems, while its compact design (29 mm x 366 mm x 35.4 mm) allows flexible installation even in narrow control cabinets. The IP65-rated aluminum housing is reinforced with diecast zinc end caps and a PMMA lens cover for durability in harsh industrial environments.
Engineered to function reliably in a wide operating temperature range from -15°C to 55°C and humidity levels up to 95%, the MLC310R20-300 is trusted by OEMs and safety integrators for high-performance guarding in space-constrained operations. For additional product certifications, mounting guidance, and system integration documentation, please refer to the official Leuze website.
The Leuze MLC310R20-300 Safety Light Curtain is commonly used in compact machine areas where precise hand protection is critical. Applications include desktop automation systems, testing stations, light-duty pick-and-place machines, and fixture-based assembly zones. The model is particularly effective in workspaces where traditional full-height curtains are impractical due to space limitations or ergonomic concerns.
Indian engineers appreciate this model’s ease of installation through groove mounts, device columns, and swivel brackets. The quick-connect M12 interface ensures rapid deployment, while LED indicators simplify diagnostics and maintenance tasks. Thanks to its optical sync and built-in safety functions like automatic restart and channel switching, system builders can confidently use it in high-mix, high-speed environments without interference issues.
For buyers seeking a compact, durable, and technically advanced solution, the Leuze MLC310R20-300 Safety Light Curtain offers unmatched reliability and protection. Get in touch today for pricing support, expert integration advice, and the best deals on safety automation products from Leuze.
