Mechanical Characteristics
Mechanical characteristics such as center conductor protrusion and pin depth are not 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 3-6 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. Refer to 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).
