Integrated resistive safety edges stand out from other edges because they are easy to fit and modify. The safety edge is rubber extrusion with a conductive polymer, EPDM, in the switching chamber. An 8K2Ω resistor in the end cap is measured when the safety edge is connected. When pressure is applied to the rubber extrude, the switching chamber closes and the circuit shorts. This is how the hazards are detected.
