Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth
are not warranted performance specifications. They are, however, important
supplemental characteristics related to electrical performance. Keysight
Technologies verifies the mechanical characteristics of the devices in this kit
with special gaging processes and electrical testing. This ensures that the
device connectors do not exhibit any improper pin depth when the kit leaves
the factory.
“Gaging Connectors” on page 3-7 explains how to use gages to determine if
the kit devices have maintained their mechanical integrity. Refer to Table 2-2
on page 2-4 for typical and observed pin depth limits.
Pin Depth
Pin depth is the distance the center conductor mating plane differs from being
flush with the outer conductor mating plane. See Figure 2-1 . Some coaxial
connectors, such as 2.4 mm and 3.5 mm, are designed to have these planes
nearly flush. Type-N connectors, however, are designed with a pin depth offset
of approximately 5.26 mm (0.207 inch), not permitting these planes to be flush.
The male center conductors are recessed by the offset value while the female
center conductors compensate by protruding the same amount. This offset
necessitates the redefining of pin depth with regard to protrusion and
recession.
Protrusion refers to a male type-N connector center conductor having a pin
depth value less than 5.26 mm (0.207 inch), or a female type-N connector
center conductor having a pin depth value greater than 5.26 mm (0.207 inch).
Recession refers to a male type-N connector center conductor having a pin
depth value greater than 5.26 mm (0.207 in), or a female type-N connector
center conductor having a pin depth value less than 5.26 mm (0.207 inch).
