Safety Edges

With Formula System safety edges there is less to go wrong. All the electronics are contained in the edges. The cable to the edges is a standard flex so if the cable breaks you can replace it easily. The Formula Systems patented diagonally offset beam pattern ensures that the whole of the entrance is protected. It also means a faster scan time which allows the edges to respond in 45ms to a beam interrupt.
