Typical proximity sensors can detect different types of metals, but all with very different detection ranges. The range for copper can be up to 70% less than the maximum range of a sensor. The range can even vary slightly between different types of the same metal, for example, mild steel or carbon steel. Reduction Factor 1 sensors have multiple sensing coils that work together to detect multiple metals in the same range. Combined with IO-Link, this provides a sensor with unmatched flexibility that can be configured for many applications. Don’t be limited by a switch.
