The PRDA series inductive proximity sensors are PTFE coated for high heat resistance and prevention of malfunctions caused by welding spatter. The sensors also feature long sensing distances and excellent noise immunity with a specialized sensor IC developed by Autonics. The sensors are ideal for welding applications and can be used as an alternative to spatter-resistant limit switches.

The Characteristic of Spatter-Resistance Type

The hot arc from arc welding machine is adhesive even with metals or plastics. Therefore, normal proximity sensor might have malfunction even though there are no sensing object if the arcs are put on the sensing surface. The arcs are not adhered on the sensing part of the spatter-resistance type proximity sensor as the part is coated with PEFE against thermal resistance. Also, the protection cover sold optionally has the same function.
