5-pin XLR connector

A five-pole XLR form has its own contact arrangement; the housing does not identify what a device sends through it.

Also called 5 pole XLR XLR5 five pin XLR

XLR names a family, not one signal.

Look for

Compare five contact positions, housing key and latch features with the exact device manual.

What the drawing does not prove

Dots below the body show pole count only; pin location and number are deliberately not drawn.

Pole count, mating gender and device signal assignments must all be confirmed from the exact part.

No fabrication dimensions, conductor routing, guaranteed fit or device approval. For electrical, power and optical interfaces, follow the original equipment instructions.

The useful distinction

Recognize it. Then verify it.

A five-pole XLR form has its own contact arrangement; the housing does not identify what a device sends through it. [C126A]

The manufacturer lists latch-lock retention for that connector. [C126B]

The drawing linked from the NC5MXX product page separates a five-position end view from two longitudinal profiles. Its drawing number is ST-NC5MXX, while the main title field reads NX5MXX. [C126C]

What is not established

This field note does not approve a connection, publish a pinout or provide a measured template. Use the linked source scope and the checklist as a documentation starting point.

Five-position XLR source study

The new study follows the end view on the sheet linked from Neutrik NC5MXX. The source drawing number and main title are inconsistent: ST-NC5MXX versus NX5MXX. This discrepancy stays visible and no current mating dimensions are asserted.

XLR and DIN are different five-position examples

The comparison includes a five-pole DIN part and a five-pole XLR part to show why contact count cannot name the connector family or service. Nothing here designates a particular XLR-equipped device as DMX, audio or an adapter target.
