RP-N-Type coaxial connector

RP-N-Type is a reverse-polarity N-Type RF interface documented as distinct from conventional N-Type.

Also called RP-N Reverse-polarity N-Type RP N connector

Reverse polarity changes the interface contact arrangement; do not assume standard N-Type mating.

Look for

Check the center-contact arrangement and product labeling before treating an N-Type-looking interface as standard or reverse polarity.

The useful distinction

Recognize it. Then verify it.

RP-N-Type is a reverse-polarity N-Type RF interface documented as distinct from conventional N-Type. [C225A]

Source-scoped identification facts

Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Recorded variant and source limits
  • Coupling style or polarity identity does not establish cable type, impedance, frequency range or system compatibility for a specific assembly.
  • No fabrication dimensions or mating-face contact locator is published.

A boundary, not an omission to guess around.

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.
Trace a supported connection class →

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.
