Kaman Precision Products has announced the availability of its improved ThreadChecker for the automotive industry. The line of non-contact application-specific sensors aims to provide reliable verification of thread presence or absence in most electrically conductive materials.
The ThreadChecker is a teachable eddy current inspection tool, widely used for thread detection, material sorting, plating presence and absence of heat treatment. Any physical property difference that relates to material conductivity is readily detected.
The tool is designed for use in any automated inspection process in the automotive industry. Consisting of a single electronics module compatible with any probe/material combination, the tool can check threads regardless of part cleanliness.
Designed specifically for in-die use, it features four internal thread probes, ranging from 4mm to 10mm, and two external thread probes, 6mm and 8mm. Available with a DIN rail mounting option, the tool is CE compliant and features IP67 rated probes and electronics.
The ThreadChecker is available with switched and analog outputs. With the switched output option, the sensor is wired to a PLC or other controller, programmed to alarm when no thread is detected. As an alternative, users can monitor the analog voltage and program the PLC or other control device with limits suitable for the application.
