New Weld Nut Sensors from Turck

TURCK’s magnetic-inductive weld nut sensors provide efficient and economical detection of weld nuts in automotive applications. The sensors detect ferromagnetic components, such as nuts, bushings and spacer sleeves, to ensure these components are present before robotic welding occurs. These sensors are less complex than existing devices that require additional software or electronics to detect the target.

Weld nut sensors are programmed to differentiate between the nut and the sheet metal on which it is located, delivering accurate component detection. At the push of a button, the sensor “learns” the status of the weld nut/sheet metal combination (along with the status of the sheet metal alone). The TURCK weld nut sensor may be mechanically protected with a stainless steel sleeve (not included), which also acts as a guide to keep the weld nut in place.

Weld nut sensors are available in two versions offering different signal intensities and diameters to adapt to a wide variety of operating environments and material characteristics. The sensors also feature a rugged IP 67 rated housing that protects internal components from harsh welding zone conditions. Plus, the sensors offer temperature compensation to withstand the thermal changes common in welding environments.
