3.5 mm Mono Metal Jack Plug — No name WTY0010, audio connector, metal housing

3.5 mm Mono Metal Jack Plug — No name WTY0010 is a compact mono audio connector designed for single-channel signal transmission. The plug features a 3.5 mm mono tip and a metal housing that improves mechanical strength and provides basic shielding against interference. It is intended for repair, replacement or assembly of mono audio cables used with instruments, small audio devices and DIY electronics where a compact, durable connector is required.

Advantages

The metal housing offers improved durability and wear resistance compared with plastic alternatives, while the mono 3.5 mm tip ensures compatibility with standard mono audio sockets. The plug’s compact size makes it suitable for tight spaces and lightweight applications. Its simple construction allows for straightforward soldering or connection during cable assembly and repair.

Suitable for

• Repairing mono instrument cables
• Building DIY mono audio leads
• Connecting small audio devices with mono inputs/outputs
• Electronic projects and prototypes requiring a compact audio connector

Key specifications

• Connector type: 3.5 mm mono (single-channel) plug
• Housing material: metal (mechanical durability and shielding)
• Contact finish: conductive metal tip suitable for audio signals
• Mounting/termination: solder-type connection for cable assembly
• Form factor: compact inline plug for cable ends

How to use

Prepare the cable by stripping the outer jacket and exposing the single signal conductor and any shield or ground. Tin the exposed conductor and the connector’s solder tabs. Insert the conductor into the plug and solder it to the designated tip contact, ensuring a secure mechanical and electrical connection. Assemble the metal housing over the soldered joint and fasten according to the plug’s construction to provide strain relief and shielding. Test continuity and signal transmission before finalizing installation.

Usage recommendations

Use this 3.5 mm mono metal jack plug for low-voltage audio applications and avoid exposure to moisture or corrosive environments. For best results, use appropriate soldering tools and heat-shrink tubing or cable clamps for strain relief. Verify polarity and connector orientation before soldering to prevent wiring errors.
