Turck sensors differentiate between metal types

Turck has announced that its analogue and proximity sensors have been enhanced to differentiate between varying types of metal during detection, independent of their distance from the sensor.

Available in ring and flat housings, these material detection sensors provide sensing ranges up to 11mm and are suitable for stamping, die cutting and metal sorting applications where different metal types must be readily and accurately detected.

The analogue and material detection sensors use inductive coils whose radio-frequency fields are influenced differently for each metal type.

The signal difference is then converted into a 0-10VDC analogue signal to signify which type of metal is being detected.

An operating temperature rating of -10C to +70C makes the sensors useful in cold pilger rolling mills used for drawing seamless pipes, according to the company.
