C-5 Connector Pin Depth Precautions Appendix C — Connector Care
C-4 PN: 13000-00164 Rev. K ML248xx, ML249xA MM
Based on RF components returned for repair, destructive pin depth of mating connectors is the major cause of
failure in the field. When an RF component is mated with a connector having a destructive pin depth, damage
will likely occur to the RF component connector.
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 C-1 on page C-4
below) in the “+” region of the gauge (see Figure C-2 on page C-3 ), 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.
Over Torquing Connectors
Over torquing connectors is destructive; it may damage the connector center pin. Finger-tight is usually
sufficient, especially on Type N connectors. Never use pliers to tighten connectors. For other connectors, use
the correct torque wrench.
Note A destructive pin depth has a center pin that is too long in respect to the connector’s reference plane.
