• Terminating or repairing headphone cables
• Custom audio cable assembly for portable players and smartphones
• In-car audio and auxiliary input connections
• Small electronics and audio projects requiring a male 3.5 mm stereo plug

Key specifications

• Connector type: 3.5 mm TRS (stereo) male
• Housing material: metal
• Contact plating: gold-plated contacts for corrosion resistance
• Application: cable termination, repair, custom assemblies
• Compatibility: standard 3.5 mm stereo jacks and devices

How to use

Prepare the audio cable by stripping the outer jacket and isolating the inner conductors according to the cable's color code. Insert or solder the conductors to the appropriate terminals of the connector following the manufacturer’s wiring convention for tip (left), ring (right) and sleeve (ground). Reassemble the metal housing and ensure the strain relief clamps the cable securely. Verify continuity and correct channel wiring with a multimeter or by testing with an audio source and headphones before final use.

Usage recommendations

For reliable long-term performance, avoid exposing the connector to prolonged moisture and clean contacts occasionally with a contact cleaner. Use proper soldering techniques and appropriate heat to prevent damage to the connector and insulation. When used in mobile or in-vehicle environments, ensure the housing is tightened and the cable strain relief is properly engaged to minimize mechanical stress.
