Safety light curtain

A safety light curtain is a non-contact industrial safeguarding device that creates a protective barrier using multiple infrared beams. When a person or object enters the hazardous zone and blocks the beams, the system instantly outputs a stop or control signal to prevent mechanical injuries.

Our safety light curtain series complies with IEC 61496 safety standards and delivers strong anti-interference performance, fast response, and high operational stability. With multiple beam pitches (10–80 mm) and a wide range of protection heights, the product supports finger, hand, arm, and full-body protection across various industrial applications.

A variety of output options (NPN, PNP, relay, and controller-based outputs), compact construction, and flexible mounting methods make the system suitable for small precision machines, automated production lines, stamping and forming equipment, and other hazardous industrial environments. It provides a reliable, efficient, and cost-effective safety solution for modern manufacturing.
