Light Curtain

Light curtain is a non-contact safety sensor that creates an invisible infrared protection barrier around hazardous machine areas. It is suitable for factories, automation lines, press machines, cutting equipment, robotic cells, packaging systems, and other machinery where operator safety is critical. By detecting hands, arms, or objects entering the danger zone, a light curtain can help trigger machine stop signals, reducing the risk of injury, equipment damage, and production accidents while supporting safer and more efficient industrial operation.

Light Curtain FAQ

Q1: What is the best light curtain for machine safety protection?

The best light curtain depends on the machine type, protection height, beam spacing, and required output. For press machines, cutting machines, and automated equipment, choose a safety light curtain with fast response, reliable NPN/PNP output, and suitable protective height.

Q2: How to choose the right beam spacing for a safety light curtain?

Smaller beam spacing is better for finger or hand protection, while larger beam spacing is suitable for body or access area detection. For close machine guarding, 10mm or 20mm beam spacing is commonly used.

Q3: Which light curtain is suitable for automated production lines?

For conveyor lines, packaging lines, and assembly lines, choose a light curtain with stable detection, fast response time, and suitable detection distance. It helps protect operators while allowing materials to move through the line.

Q4: What should I check before buying a safety light curtain?

Check beam spacing, protective height, detection distance, output type, response time, IP rating, and installation method. These factors help ensure the light curtain matches your machine safety and industrial automation requirements.
