This 3.5mm (1/8") 4-Pole TRRS Audio Jack Terminal Block provides a simple solder-free way to connect individual wires to a four-pole audio connection, with screw terminals for stereo audio, microphone and ground connections.
One truth about working with audio is you always need the cable or adapter you don't have in your toolbox. That's why we love these terminal-block audio connectors so much. No soldering required! Use stranded or solid core wire and a small screw driver to create custom wiring jigs.
This is the 3.5mm (1/8") 4-Pole (TRRS) Audio Jack Terminal Block. TRRS stands for Tip, Ring, Ring, Sleeve. It has four total pins - three signal and a ground as opposed to a more common stereo jack's three. This type of connector is most often used in smartphones & cell phones to provide stereo audio and one mic channel.
Please note that the green block labels it as GND-blank-Right-Left which is the most commonly used order. However, it would be more technically correct to just label it Sleeve-Ring-Ring-Tip: goes in the same order as the four contacts on the plug.
We also stock the matching 4-Pole Audio Plug Terminal Block.
