Proximity Sensors Differentiate Metal Types

TURCK announces their analog+ 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 11 mm and are well suited for stamping, die cutting and metal sorting applications, where different metal types must be readily and accurately detected.

The analog+ material detection sensors use inductive coils whose RF fields are influenced differently for each metal type. The signal difference is then converted into a 0 to 10 VDC analog signal to signify which type of metal is being detected. Additionally, a wide operating temperature rating of -10 to 70°C makes these sensors particularly useful in cold pilger rolling mills used for drawing seamless pipes.
