These sensors deliver an alternative to optical or vision-based systems, which can often malfunction due to residue, such as dirt and weld-splatter, and frequently changing lighting conditions in welding zones. The TURCK weld nut sensor can be mechanically protected with a customer-supplied stainless steel sleeve, which also acts as a guide to keep the weld nut in place. Weld nut sensors are easily programmed to differentiate between the nut and the sheet metal on which it is located, by using a teach adapter or by simply shorting the leads.
