3.5mm Metal Audio Plug 4-Pole TRRS Connector

The 3.5mm Metal Audio Plug 4-Pole TRRS Connector is a compact connector designed for applications requiring a 3.5mm four-contact audio connection. The TRRS (Tip-Ring-Ring-Sleeve) configuration provides four separate electrical contacts, allowing audio and additional signal connections to be carried through a single compact plug.

The metal-bodied construction makes this connector suitable for DIY cable assembly, electronics repair, custom audio projects, and prototype development. It can be connected to suitable wires through soldering to create custom cables or repair damaged 3.5mm TRRS connections.

A typical TRRS arrangement can provide connections for left audio, right audio, ground, and an additional microphone or control signal. However, the exact pin assignment can vary depending on the equipment and wiring standard, so the connector should be wired according to the requirements of the target device.

How to Use

1. Identify the required TRRS pin configuration for the target device.
2. Open or prepare the metal connector for cable assembly.
3. Strip and prepare the wires that will be connected to the plug.
4. Match each wire to the appropriate TRRS contact.
5. Solder the wires securely to the corresponding terminals.
6. Check for solder bridges or unwanted connections between adjacent contacts.
7. Secure the cable and connector housing properly.
8. Test the completed connection with the intended audio or electronic equipment.

Important Notes

• TRRS pin assignments can vary between devices and wiring standards.
• Verify the required pinout before soldering the connector.
• Avoid excessive heat during soldering to prevent damage to the connector or cable insulation.
• Make sure adjacent contacts do not become shorted during assembly.
• The metal body may need to be properly secured to prevent cable strain from reaching the solder joints.
• This is a connector component and does not include a pre-assembled cable unless specifically stated.
• Product appearance and internal construction may vary slightly between manufacturing batches.
