Sexed Connectors

In Type-N and precision 3.5mm 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.
50 Ohm 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.
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 (Figure E-5).
