About the ThreadChecker™

Kaman’s improved ThreadChecker consists of a single electronics module compatible with any probe/material combination. Designed specifically for in-die use, it provides rugged, reliable verification of thread presence or absence in nearly any electrically conductive material. With Kaman’s proven eddy current technology at its core, threads can be checked regardless of part cleanliness, reducing the cost of implementation.

Other features ThreadChecker™

  • Universal electronics for any probe/material combination
  • Push button teach
  • Both switched and analog outputs
