    FAQ

    Yes. A light curtain sensor is a type of machine guard because it creates a non-physical barrier that stops the machine when the beams are broken.

    To maintain a safety light curtain, keep the sensor clean, check that the emitter and receiver stay properly aligned, inspect cables and mounting brackets for damage, and regularly test the stop response to make sure it activates correctly when a beam is blocked.

    Industrial production involves high-speed, powerful, and dangerous moving parts. Safety light curtain sensors can immediately stop the press when any beam is blocked, preventing hand injuries and providing necessary protection for operators.

    Reliable photoelectric light curtain, tough yellow shell
    Needed a compact photoelectric light curtain for an automated packing line conveyor pinch point. The IP55 enclosure holds up fine against the daily dust in our shop. The cables coming out of the aviation heads are slightly stiff to route around tight machine corners, but the tracking is spot on. Good budget safety upgrade for us.
