Kaman's ThreadChecker is a new non-contact sensor range designed to check both internal and external thread presence for critical parts manufacture and automated assembly line applications. Available exclusively in the UK from Ixthus Instrumentation, the range consists of a choice of IP67-rated eddy current probes and an electronics module with both output and visual indication of whether or not the thread is present.
Four internal probes measure threaded holes to 14mm diameter and two external probes suit external threads to 10mm diameter. Available to suit most metals, the robust probes operate at temperatures up to 70degC and, as Kaman's rugged and reliable eddy current technology does not require a high level of part cleanliness, operation in hostile and dirty environments is guaranteed.
CE-compliant, the ThreadChecker range features both switched relay and analogue outputs that can be wired to a PLC programmed to alarm when no thread is detected. A teach function, using an integral pushbutton and a three-state LED, is also available for manual set-up and operation. The electronics module can be panel- or DIN rail-mounted.
Threadchecker is part of Kaman's GageProx family, which uses a single-ended input and fixed-gain output technology, useful for set-it-and-forget-it gauging applications in the metal-forming industry for in-die parts inspection. It has applications for automated assembly and testing in automotive and white goods manufacture, in addition to many other demanding thread presence measurement applications in machine shops and clean rooms.
