RP-TNC coaxial connector engineering reference

Reverse-polarity family boundary; standard and reverse-polarity TNC are not collapsed into one mating interface. Amphenol RF 122108RP is a straight RP-TNC plug. Its table reports brass body; nickel finish, phosphor-bronze contact; gold finish, cable-crimp construction; crimp contact termination, threaded coupling, 50-ohm impedance, a 11-GHz frequency ceiling and 500 minimum mating cycles. It identifies a PTFE insulator. These are exact-part manufacturer specifications, not family-wide ratings or independent test results.

How to read this profile

V40 publishes no center-contact face locator; reverse polarity is kept as an explicit interface distinction.
