    FAQ
    ❯

    Light curtain sensors are used for machine safety and object detection. They protect operators from hazardous machinery and are also used for sizing, positioning, and presence detection in automated systems.

    ❯

    A safety light curtain sends multiple infrared beams from an emitter to a receiver. When any beam is blocked by a hand, object, or part, the system detects the interruption and sends a signal—either to stop a machine or to perform a detection task.

    ❯

    Detection capability depends on the resolution. The light curtain can detect objects as small as a finger (high-resolution), a hand, or even a full body presence.
