TURCK has enhanced the functionality of its analog+ proximity sensors to differentiate between the types of metal being detected—independent of the distance from the sensor.
Available in ring and flat housings that can provide up to 11 mm of sensing range, these sensors function well in stamping, die cutting and metal sorting applications where different metal types are frequently found.
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 that draw seamless pipes.
