Mini Circuits manufactures a comprehensive line of connector gauges for measuring the critical interface dimensions of coaxial connectors .Testing the interfaces of connectors on any device at incoming inspection is not only highly recommended, it is definitely a necessity. Interfaces not meeting the specifications will lead to degraded specification of the components. In addition, these out of specification interfaces may damage the connectors of mating components or ruin the connectors of the test equipment. These connector gauges consist of an exclusively developed dial indicator with appropriate bushings and pins, designed to mate with the specific connector under test. The indicator is set to zero by a calibration block (master).When engaged to a connector, it measures the specific interface dimension from a reference plane.
