Concentricity - male connector
Mating plane surfaces
Flat contact between the connectors at all points on their mating plane surface is required for a
good connection.
Look for deep scratches or dents, and for dirt and metal particles on the connector mating plane
surfaces. Also look for “dings” on the mating plane surfaces of the center and outer conductors,
and for signs of damage due to misalignment and excessive or uneven wear.
A light burnishing of the mating plane surface is normal. This 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 affects electrical or
mechanical performance.
Clean and inspect the connector again if it shows:
– Deep scratches or dents
– Particles clinging to the mating plane surface
– Uneven wear
Damaged connectors
If you find a damaged connector, try to determine the cause of the damage
before
connecting a
new, undamaged connector in the same configuration. Damaged connectors should be discarded.
Connector wear
Connector wear eventually degrades performance. The more use a connector gets, the faster it
wears and degrades. The wear is greatly accelerated when connectors are not kept clean. When
your connectors become worn, replace them.
