Light curtains are not new to the market but they are less common; two rows of LED infrared lights fire in sequence to cover an entrance way. These systems are perfect for fast moving gates or very large heavy gates, where you do not want the gate to ever come into contact with an obstruction such as a vehicle or pedestrian.
This is the only type of photocell which can pass current health and safety regulations on its own as the whole entrance is covered, making it impossible to reach the gate without triggering the safety device.
Below are details on the two different types of safety light curtains available.

The Light Curtain consists of a self-contained transmitter detector and receiver detector, which are to be positioned opposite each other. The detectors are housed in a weather resistant aluminium profile available in a slim line design (12 x 30 mm). The advanced automatic signal tracking feature ensures that no onsite set up or adjustments are required. The signal level of each individual channel is adjusted automatically, which compensates for misalignment and contamination during operation.
