3.5mm to 6.35mm Cable - 1.8m

AUD-35-635-1.8M

3.5mm jack to 6.35mm jack audio cable. Length 1.8 metres.

Length: 1.8 m
Connectors: 3.5mm / 6.35mm

In-depth technical details

3.5mm and 6.35mm audio jacks are TS, TRS, or TRRS depending on the number of insulating bands visible on the plug -- TS (mono) has one band, TRS (stereo, or balanced mono line-level) has two, TRRS (adds a mic channel) has three. The band count on the actual plug is the real, checkable way to tell which wiring a cable carries.

End A

3.5 mm jack

01 Tip Carries the left channel in stereo use, or the whole signal in mono.
02 Ring The right channel. Crackle when you wiggle the plug is this ring losing contact.
03 Sleeve The common ground — the voltage reference the signal is measured against.
04 Insulating bands The black bands keep the conductors apart. Without them the channels short to ground.
05 Strain-relief boot Stops the wires flexing where they leave the plug — the exact point most cables fail.
06 Outer jacket The outer sheath protecting the conductors inside from abrasion and moisture.

How it works

Unbalanced audio cable

Two independent conductors (left and right) share one ground braid. Neither channel gets noise cancellation, which is why hum and hiss appear after a few metres.

01 Left and right conductors Each channel carries its own signal, referenced to the shared ground.
02 Shield A grounded conductive wrap that absorbs electromagnetic interference before it reaches the signal.
03 Outer jacket Protects everything inside mechanically. It plays no electrical role.

From the published standard

How it works

A jack plug carries the signal on three parts: the tip for the left channel, the ring for the right, and the sleeve as common ground, separated by insulating bands. The 3.5 mm and 6.35 mm sizes are electrically identical and differ only in size, which is why an adapter between them is just wire. Crackle when the plug is moved is worn contact at the ring, not a fault in the equipment.

Contacts: Tip (left), ring (right), sleeve (ground)
3.5 mm vs 6.35 mm: Electrically identical, different size only
Balance: Unbalanced — susceptible to hum on long runs
