RP-TNC coaxial connector

RP-TNC is the reverse-polarity TNC interface with the same threaded coupling family but reversed center-contact convention.

Also called RP-TNC Reverse-polarity TNC

Standard TNC and RP-TNC should be distinguished before mating or specifying adapters.

Look for

Inspect the center-contact arrangement and product label, not only the threaded outer body.

The useful distinction

Recognize it. Then verify it.

RP-TNC is the reverse-polarity TNC interface with the same threaded coupling family but reversed center-contact convention. [C227A]

Amphenol RF identifies 122400RP as a straight 50-ohm RP-TNC jack with threaded coupling and rear bulkhead mounting. [C227D]

For 122400RP, the product page separately lists crimp contact termination and cable-solder termination style. [C227E]

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. [C227X]

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.

What is not established

This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
