Use, Maintenance, and Care of the Devices
Visual Inspection
Inspect the Mating Plane Surfaces
Flat contact between the connectors at all points on their mating plane surfaces is required for
a good connection. See
Figure 2-1 on page 2-3 . Look especially for deep scratches or dents,
and for dirt and metal particles on the connector mating plane surfaces. Also look for signs of
damage due to excessive or uneven wear or misalignment.
Light burnishing of the mating plane surfaces is normal, and is evident as light scratches or
shallow circular marks distributed more or less uniformly over the mating plane surface. Other
small defects and cosmetic imperfections are also normal. None of these affect electrical or
mechanical performance.
If a connector shows deep scratches or dents, particles clinging to the mating plane surfaces,
or uneven wear, clean and inspect it again. Devices with damaged connectors should be
discarded. Determine the cause of damage before connecting a new, undamaged connector in
the same configuration.
Inspect Female Connectors
Pay special attention to the contact fingers in the female center conductor. These can be bent
or broken, and damage to them is not always easy to see. A connector with damaged contact
fingers will negatively affect electrical performance and must be replaced.
NOTE Inspection is particularly important when mating nonprecision to precision
devices.
