Complete interface dimensions of the connectors are shown at the end of this chapter. The important measurements are marked clearly for every connector series:
Dimensions, highlighted in an oval shape, are recommended for verification as a minimum. The connector gauges measuring these dimensions are included in the Expanded Calibration Kit and the Professional Kit as well.
Dimensions, highlighted in a rectangular shape are recommended for verification in addition to the dimensions highlighted in an oval shape. Checking all these dimensions will guarantee optimum performance of the connectors. The necessary connector gauges to measure all those dimensions are included in the Professional Calibration Kit only.
Testing the interfaces of connectors and adapters upon incoming inspection is not only highly recommended, it is definitely a necessity. Interfaces not meeting specification 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.
Spectrum Elektrotechnik GmbH manufactures a comprehensive line of connector gauges for measuring the critical interface dimensions of coaxial connectors. These connector gauges consist of an especially adapted dial indicator with appropriate bushings and pins that are designed to mate with the specific connector under test. The indicator is zero set by a calibration block (master). When engaged to a connector, it measures the specific interface dimension from a reference plane. For every dimension of interest, a special gauge is offered. This gives the most accurate results, allows easy calibration, fast testing and helps to avoid mistakes.
A number of gauges are available. The main difference between the gauges is in the resolution, and the units of measurement, inches, or metric. Only the digital gauges can be switched from metric to inch and vice versa. Normally the Connector Gauges are supplied in an instrument case that protects them from getting damaged. In the box, there is also space for the appropriate torque wrench, which can be supplied on a separate order.
