The Leuze MLC310R20-750 Safety Light Curtain is a reliable receiver unit from the well-established MLC 300 series, tailored to safeguard machines where accurate hand or finger detection is critical. It features a 750 mm protective field height with a tight 20 mm resolution, making it effective for preventing operator access to dangerous zones in robotic enclosures, palletizing stations, and semi-automated machinery. Synchronization between transmitter and receiver is optical, meaning no sync wiring is needed, reducing installation time and error potential. Integrated safety functions such as automatic start/restart and channel switching offer enhanced protection during restarts or signal interference.
This model operates on a robust 24 V DC supply with ±20% tolerance and consumes a maximum of 150 mA. It includes 2 safety-related switching outputs (OSSDs) using PNP transistor logic, capable of handling switching voltages up to 22.5 V and a max current of 380 mA. The unit delivers a response time of 14 ms, ensuring rapid action in safety-critical events. It connects via a standardized 5-pin M12 male connector for ease of wiring with industrial controllers. Measuring just 29 mm x 816 mm x 35.4 mm, the slim profile fits comfortably in tight machine spaces. The aluminum housing, PMMA lens cover, and diecast zinc end caps offer IP65-rated durability for rugged environments.
With an operating temperature range of -15°C to 55°C and tolerance to 95% non-condensing humidity, the MLC310R20-750 performs reliably in harsh industrial settings. For datasheets, wiring diagrams, or CE declarations, please visit the official Leuze website.
The Leuze MLC310R20-750 Safety Light Curtain is designed for industrial environments where medium-height protective coverage is essential for safeguarding machine access points.
