Built by Leuze, the MLC300T20-1650 combines optical precision with rugged engineering for demanding safety applications. It offers a tight 20 mm resolution and a tall 1,650 mm protective field height, making it ideal for detecting fingers or hands at access points of automated machines. The device operates effectively within a 0 to 15 meter sensing range, using a 940 nm pulsed infrared LED light source to ensure high immunity to ambient lighting and electrical interference.
The transmitter draws just 50 mA at 24 V DC (with a -20% to +20% tolerance), making it energy-efficient and compatible with most industrial control systems. It supports optical synchronization with its receiver, reducing wiring complexity and installation time. A standard M12 5-pin male connector ensures easy integration. The enclosure is constructed with an aluminum housing, PMMA lens cover, and diecast zinc end caps, delivering IP65 protection for use in dusty or humid environments.
Measuring 29 mm x 1,716 mm x 35.4 mm and weighing 1,800 grams, the MLC300T20-1650 is built for vertical mounting via brackets, columns, or swivel supports. The built-in LED indicators simplify alignment and diagnostics. Additional protection features include short-circuit and overvoltage protection, enhancing operational safety and lifespan. Trusted by system integrators and OEMs, this model balances precision, durability, and ease of installationβmaking the Leuze MLC300T20-1650 Safety Light Curtain a reliable choice for critical hand-protection zones.
