Safety edges are used as pinching and shearing protection, and they are suitable for machining tools, personnel lifts, lifts and heavy doors. Safety edges are safety equipment subject to type approval, and comprise the edge and a control unit. The construction enables the use of the edges as a safety system..
Safety edges can be linked end-on-end, and the final edge must have a terminating resistor. The edges can also be used as a switch without a terminating resistor, but in that case, they are not allowed to be used as safety equipment.
