Questions and answers
Why there is only 2 wires showing in the electrical connection for the KI0054 proximity sensor. I have 3 wires
The IFM KI0054 proximity sensor uses a 2-wire electrical connection because it operates with two-wire technology, meaning it is designed to function without a dedicated third wire for ground or signal. The available three wires may refer to different connection options, but for two-wire devices, only two are used for both power supply and signal transmission. The manual also notes that such devices are not short-circuit proof or overload protected, requiring verification of safe operation after a short circuit.
