Female connectors
The precision type-F interface is defined by HP type-F Connector
Interface A-1250-9059-1 rev. C. The inside diameter (ID) will ensure the
specified performance with 0.77 to 0.86 mm (0.030 to 0.034 in) diameter
male conductor. In addition, the ID will accept up to a 1.07 mm (0.042
in) diameter male conductor without compromising subsequent
electrical performance with the 0.77 to 0.86 mm (0.030 to 0.034 in)
diameter male conductor or degrade the electrical contact with the 0.56
mm (0.022 in) diameter male conductor.
CAUTION
Many type-F “feedthrough” connectors use the cable center conductor
as the male pin. These cable center conductors often exceed the
1.07 mm (0.042 in) maximum pin specification and will destroy the
calibration kit female standards. Damage will also occur to the female
standards if the pins of the “feedthrough” connectors are not properly
chamfered.
