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 the electrical performance of
devices. Keysight Technologies verifies the mechanical characteristics of the
devices with special gaging processes and electrical testing. These processes
ensure that the device connectors do not exhibit any excess center conductor
protrusion or improper pin depth when the module leaves the factory.
“Gaging Connectors” on page 4-9
explains how to use pin-depth gages. Refer
“Typical Pin Depth Values” on page 5-26
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 connector mating plane. The pin depth of a connector can
be in one of two states: protrusion or recession. The pin depth for a 3.5 mm
connector is shown in
, although the description also applies to
1.85 mm, 2.4 mm, and 2.92 mm connectors. The pin depth for 4.3–10 is shown
.The pin depth for 7–16 is shown in
. The pin depth for
Type-N connectors is shown in
. Typical pin depths for ECal
connectors are listed in
“Typical Pin Depth Values” on page 5-26
.
Protrusion
occurs when the center conductor extends beyond the outer
conductor mating plane. It reads as a positive value on the connector gage.
Recession
occurs when the center conductor is set back from the outer
conductor mating plane. It reads as a negative value on the gage.
No protrusion of the center conductor shoulder is allowable on any 7 mm
connector when the slotted collet is removed. The slotted collet must be removed
before measuring the pin depth.
