Pin Depth Tolerances
The center pin of RF component connectors has a precision tolerance
measured in “mils” which is equal to 1/1000 inch (0.001”) or
approximately 0.02540 mm.
V connectors have a higher precision tolerance measured in “tenths” or
1/10,000 inch (0.0001”) or approximately 0.00254 mm.
Connectors on test devices that mate with RF components may not be
precision types and may not have the proper depth. They must be
measured before mating to ensure suitability and to avoid connector
damage.
When gauging pin depth, if the test device connector measures out of
tolerance (see
Table 3-2
) in the “+” region of the gauge (see
Figure 3-2
on page 3-9
), the center pin is too long. Mating under this condition will
likely damage the termination connector.
On the other hand, if the test device connector measures out of
tolerance in the “–” region, the center pin is too short. While this will not
cause any damage, it will result in a poor connection and a consequent
degradation in performance.
