Specifications
Agilent Technologies guarantees that your adapters will equal or exceed the following specifications in the
+20
to +26
C (+68
to +79
F) temperature range.
The allowable recession of the center conductor of the NMD-3.5 mm (f) connector is –0.0006 to –0.0022
inches (–0.015 to –0.056 mm) below the mating surface of the outer conductor.
The allowable pin position for type-N connectors is:
male = –0.2075 to –0.2079 inch (–5.2705 to –5.28066 mm)
female = +0.2061 to +0.2065 inch (+5.23494 to +5.2451 mm)
In a mated pair of type-N connectors, the center conductor’s mating plane is offset from the outer
conductor’s mating plane by 0.207 inch (5.2578 mm) in the direction of the male connector. See
Figure 1 on
page 3
.
Zero the gages before each use by attaching the appropriate gage master to the end of the gage, torquing
the connection to 12 in-lb with a 3/4 inch torque wrench, and adjusting the dial on the face of the gage so
the gage reads zero.
Both type-N gages, male and female, read zero when the center conductor to outer conductor offset is
nominally 0.2070 inch (5.2578 mm).
When gaging a male connector, the actual recession of the center conductor is –0.2070 inch
plus
the
reading on the gage.
When gaging a female connector, the actual recession of the center conductor is +0.2070 inch
plus
the
reading on the gage.
Example: for a gage reading of –0.0001 inch, the following is true:
