6.35 mm TS connector

The 6.35 mm TS phone plug has two conductive sections.

Also called quarter inch TS 6.35mm mono 1/4 TS

A quarter-inch plug is a size, not a complete audio specification.

Look for

Distinguish its single insulating band from the two-band TRS version. Check the equipment labeling before connecting an instrument, output or input.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

What the drawing does not prove

Band counts are documented; no geometric scale or wiring assignment.

The instrument or balanced-audio role depends on the equipment, not just the plug.

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

Figure evidence, orientation & usage rights

Uses previously recorded V112 manufacturer claim/source inspections; October 2026 supplementary public-source spot checks are documented separately, not treated as a refreshed approval.

Original Port & Cable interpretive vector, no third-party photo, copied CAD, logo or vendor drawing. Third-party product photos, logos and source drawings are not redistributed. No independent technical or rights certification is claimed.

The useful distinction

Recognize it. Then verify it.

The 6.35 mm TS phone plug has two conductive sections. [C021A]

Neutrik customer drawing ST-NP2X labels the NP2X plug shaft diameter as 6.29 mm. This is a named-part drawing value, not an exact diameter for all nominal 6.35 mm TS connectors. [C021B]

Neutrik assembly instruction BDA 142-0 labels the NP2X termination paths Tip and Shield. Those component labels do not specify the signal carried by a connected instrument or amplifier. [C021C]

Before you connect

What to check

  1. Identify the electrical role and signal level in the manual.
  2. Do not equate a physical size adapter with signal conversion.
  3. Confirm the intended wiring and destination.
