Stud and Thread Sensing

Missing studs or, worse, studs with missing threads, can mean thousands of dollars lost in scrap and time spent hand sorting. New IMI Norgren inductive stud sensors are a technological leap forward, with the widest detection range and the sturdiest construction in the industry.

Quality Checking

Are you trying to use an off-the-shelf sensor to detect whether a stud is present or not? Or, you know it’s there – but does it have threads? It’s a little late to learn that a stud has no threads when you’re trying to bolt an assembly together. Don’t trust your assembly to an ordinary all-purpose sensor. The IMI Norgren Inductive Stud Thread Detector is the only sensor engineered to be sensitive and reliable enough to actually detect threads. So you’ll never again send a welded piece through to assembly with a faulty stud!

Harsh Environments

Up, down, in, out – hundreds, maybe thousands of times a day. Every time a stud touches a sensor, the threads act like a file, slowly wearing the housing and faceplate away, unless of course, that sensor is the IMI Norgren Stud Thread Detector. With all steel housings and faceplate, this detector stands up to rigorous use. And IMI Precision Engineering has mastered the art of keeping the steel sensor tuned. Not every steel sensor can do that.

Heavy Side Loading

Automation is precise and repetitive, but it’s not always perfect. Sometimes a part comes down on a sensor just enough out of place to wallop the sensor on one side or another. This can damage or wear out an ordinary sensor, but not the IMI Norgren Stud Thread Detector. The stainless steel construction stands up to this heavy side loading, and it won’t gouge the threads either.
