Finger protection safety light curtains have a tight beam pattern with a 14mm resolution (spacing) and are designed to detect objects as small as a human finger.
Hand protection safety light curtains have a beam pattern with a 30mm resolution (spacing) and are designed to detect objects as small as the human hand.
Body protection safety light curtains have a beam pattern with 300 or 400mm resolution (spacing) and are designed to detect persons or other larger objects when they intrude into a protected area.
Mirrors allow a single pair of light curtains to protect multiple sides of an area and reduce the number of sender/receiver pairs needed. Protective columns protect a light curtain from damage and misalignment due to being hit by machinery or personnel.
Muting allows for the temporary suspension of a safety light curtain's function during the cycle of a machine/process when no hazard exists, or when objects are intentionally entering or leaving the area. For example, muting can disarm the safety function when pallets on a palletizing machine are exiting the protected area. Pre-configured and pre-wired muting arms and sensors are available to work with a wide selection of light curtains.
