Inductive Sensor checks holes for threads.

Kaman Precision Products Jun 26, 2002

Press Release Summary:

Gageprox Threadchecker can discriminate between threaded and unthreaded holes via inductive technology that measures without touching object. There is no need to clean and dry part being checked, because sensor is unaffected by moisture, oils, cleaners, grease, dirt, and grime. Setup requires teaching device to recognize threaded vs. unthreaded holes by simply inserting it into threaded hole and pressing teach button. Sensor is available in 5 and 8 mm sizes.

Original Press Release:

Kaman's New Gageprox Threadchecker Senses Thread Presence or Absence In Holes, Wins Spring 2002 Best Of Sensors Expo Award

COLORADO SPRINGS, Colorado < June 18, 2002 < Kaman Instrumentation's ThreadChecker is an application-specific sensor system designed to check for thread presence. ThreadChecker can discriminate between a threaded and an unthreaded hole via inductive technology that measures without touching the object. It provides reliable and repeatable, high-speed thread detection for nearly all thread specifications.

ThreadChecker was awarded on May 23 the bronze medal in the Best of Sensors Expo, Spring 2002 show awards, presented by the editors of Sensors Magazine.

ThreadChecker is the first application-specific configuration of Kaman's new GageProx product line. The sensors and the electronics package are designed to be rugged and reliable, meeting IP-67 specifications, and are ideal for machine shop, in-die, or other industrial environments. There is no need to clean and dry the part being checked; inductive sensors are unaffected by moisture, oils, cleaners, grease, dirt and grime.

Setup is a simple matter of "teaching" the device to recognize a threaded hole vs. an unthreaded one. The user inserts the sensor into a threaded hole and presses the "teach" button. He then inserts the same sensor into an unthreaded hole and presses the "teach" button again. A switched output and system LED will then indicate if a hole is threaded or unthreaded.

Kaman's new GageProx, of which ThreadChecker is the first release, is a family of fixed-gain linear inductive analog displacement sensors. These compact, easy-to-use sensors are ideal for automated assembly and for test and inspection. Kaman has incorporated a number of features to maximize the system's potential uses. The fixed-gain output is ideal for set-it-and-forget-it applications.

The ThreadChecker sensors are available in two unshielded sizes: 5mm and 8mm. The system features a PUR sensor cable and a DIN rail mounting option.

ThreadChecker is in stock and available immediately from Kaman Instrumentation. Prices start at $695 for single quantities.

Kaman Instrumentation, an operating unit of Kaman Aerospace, leads the industry in solving difficult industrial sensing applications when the target cannot be touched.
