INDUCTIVE NUT/THREAD DETECTION SENSORS
Norgren nut and thread detectors use inductive proximity detection technology to sense the presence of a welded nut through a blind hole in sheet metal parts. This unique sensing probe develops a radial detection field to verify that the nut totally surrounds the probe and is properly positioned. The system can often be tuned to verify thread presence and quality.
The all stainless steel probe resists weld splatter, and the sensing circuitry will not be damaged by the weld field environment. This allows the sensor to be used very close to the welding operation for detection of an incorrectly built part early in the assembly process. Norgren offers a complete line of sensor spring mounts and output converter modules.
