FAQ

Q1: Are light curtains considered machine guarding? ❯

Yes. Safety light curtains are classified as a type of machine guarding because they protect workers from hazardous machine motions by creating a non-contact protective field. When any object interrupts the infrared beams, the light curtain sends a stop signal to the machine, preventing injury.

Q2: Why is a machine guarding light curtain better than traditional mechanical guards? ❯

The machine guarding light curtain offers non-contact protection, higher speed, flexibility, and better operator convenience—making it a preferred solution in modern machine safety applications.

Q3: What is the typical response time of an industrial safety light curtain? ❯

Most machine guarding safety light curtains have a fast response time of 10–20 ms, helping ensure quick machine stopping distance.
