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

Critical Type-N Mechanical Characteristics
—
Minimum
protrusion
of the female center conductor in front of the outer
conductor mating plane is 5.182 mm or 0.204 inches.
—
Maximum
protrusion
of the female center conductor in front of the outer
conductor mating plane is 5.258 mm or 0.207 inches.
—
Minimum
recession
of the shoulder of the male contact pin behind the
outer conductor mating plane is 5.258 mm or 0.207 inches.
—
Maximum
recession
of the shoulder of the male contact pin behind the
outer conductor mating plane is 5.334 mm or 0.210 inches.
Never use a Type-N connector if the possibility of interference between the
shoulder of the male contact pin and the tip of the female contact fingers exists.
Irreparable damage will occur if a male 50
Ω
Type-N connector is mated to a
female 75
Ω
Type-N connector. If you use both 75
Ω
and 50
Ω
t Type-N
connectors, mark the 75
Ω
connectors so that they are never accidentally mated
with 50
Ω
connectors. The diameter of the center conductor, male contact pin,
and female contact hole are smaller on 75
Ω
connectors.
