Selective Metal

Unlike other TURCK proximity sensors, Selective Metal sensors are designed to pick up only non-ferrous or ferrous metals only. The selective metal capability is can be used in applications where it is important to determine whether the target it is a made from a ferrous or non-ferrous metal. Typically a second sensor is used to determine whether the part is in place and the output from the selective metal is used in the PLC logic to determine which metal is in place. TURCK does offer an analog metal distinction sensor in section F that could be used to determine the actual metal.
