Sexed connectors
In Type-N and precision 3.5 mm connectors, the position of the center conductor
in the male connector is defined as the position of the shoulder of the male
contact pin — not the position of the tip. The male contact pin slides into the
female contact fingers and electrical contact is made by the inside surfaces of the
tip of the female contact fingers on the sides of the male contact pin.

Type-N connectors
Type-N connectors differ from other connector types in that the outer conductor
mating plane is offset from the mating plane of the center conductors. The outer
conductor sleeve in the male connector extends in front of the shoulder of the
male contact pin. When the connection is made, this outer conductor sleeve fits
into a recess in the female outer conductor behind the tip of the female contact
fingers (
).

Type-N connectors
NOTE
No Type-N connector should ever be used when there is any possibility of
interference between the shoulder of the male contact pin and the tip of the
female contact fingers when the connectors are mated. In practice this means
that no Type-N connector pair should be mated when the separation between
the tip of the female contact fingers and the shoulder of the male contact pin
could be less than zero when the connectors are mated. Gage Type-N
connectors carefully to avoid damage.
