4-pin XLR connector

Four-pole XLR is a distinct keyed/latching XLR connector form.

Also called XLR4 4 pin XLR four pole XLR

Pole count identifies the connector form, not the device signal, power scheme or pin assignment.

Look for

Confirm four poles and the exact equipment application; do not adapt or wire by XLR shape alone.

The useful distinction

Recognize it. Then verify it.

Four-pole XLR is a distinct keyed/latching XLR connector form. [C206A]

The ST-NC4MXX sheet shows a keyed four-position end view separately from the connector’s longitudinal housing and boot profiles. [C206B]

For NC4MXX, Neutrik specifies solder contacts, latch retention and chuck-type cable strain relief. [C206C]

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.

Cable component, not equipment function

NC4MXX is a named male cable connector, not a finished camera-power lead. Its manufacturer-listed solder contacts, latch and strain relief describe component construction. Obtain the exact equipment cable specification rather than infer polarity or supply voltage from four positions.

Read the correct view

The end-view study is separated from the longitudinal housing profile. Contact marks are unnumbered identification cues, not a termination or polarity map. No female counterpart or installed port is reconstructed.
