Ifm Electronic 45127 Essen Sensor Manual - ((link))

No user programming is required. The sensor operates immediately after power‑up.

The sensor generates a high‑frequency electromagnetic field. When a conductive (metal) object enters the field, eddy currents are induced, reducing the oscillator amplitude. The evaluation circuit switches the output. ifm electronic 45127 essen sensor manual

Below is a structured guide that will help you install, configure, troubleshoot, and understand the sensor. No user programming is required
