These sensors deliver a cost-effective alternative to more expensive 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.
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 IP67 chrome-plated brass 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.
TURCK weld nut sensors facilitate continuous control of supply parts such as spacer sleeves and weld nuts, which are commonly used to assemble vehicle elements such as frames, U-shaped carriers and fuel tanks. The sensors’ affordable, accurate operation provides the robust production line monitoring required for error-free sheet metal processing in automotive applications.
In addition, several features of the weld nut sensor make it particularly simple to set-up and use:
“TURCK’s weld nut sensor provides smooth, reject-free production runs by cost-effectively detecting nuts and spacer sleeves, using bright LEDs to indicate any missed welding positions, which are immediately displayed on the control unit,” said Brian Tarbox, TURCK product manager. “Once the sensor confirms that all weld nuts are properly placed, the welding robots are signaled to begin welding the nuts onto the sheet metal.” Tarbox adds, “This robust design provides greater process reliability at a lower cost than optical or vision-based systems—and the sensor’s rugged construction delivers the dependable performance required in harsh automotive production environments.”
TURCK is an industry leader providing superior quality sensing, connectivity and network products to help manufacturers improve their automated processes.
