Safety Light Curtain Sensors & Light Grids
Light curtains and light grids are optical safety devices that detect a presence in their protected field and do not require any action from the machine operator to stop or limit movement. They are considered more production friendly than other safety devices, such as guarding and fencing. Light curtains are typically used for finger and hand detection where the operator is within close proximity to the equipment while light grids and spot beams are used more for body detection.
