New Products – Terminal Blocks – 1/4″ (6.35mm) Stereo Plug / Ethernet RJ45 Female Socket Push / Male Plug / 3.5mm (1/8″) 4-Pole (TRRS) Audio Plug/Jack


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 1/4″ (6.35mm) Stereo Plug Terminal Block. It’s a pretty common size and is super useful for more heavy duty connections – like a modular synth, amplifier or an electric guitar.

This is the 3.5mm (1/8″) 4-Pole (TRRS) Audio Plug Terminal Block. TRRS stands for Tip, Ring, Ring, Sleeve. It has four total conductors – three signal and a ground as opposed to a more common stereo jack’s two. This connector is most often used in smartphones & cellphones to provide stereo audio and one mic channel. On a Raspberry Pi the extra connector is used for composite video

If you need to connect an RJ45 cable (a.k.a Ethernet) to a board that doesn’t have an Ethernet jack – these adapters will come in very handy!

This is the Ethernet (RJ45) Female Jack Push-Terminal Block. There is a standard RJ45 Ethernet jack on one end, and a push terminal block on the other.

No soldering required. Just push the little buttons and slide in your stranded or solid-core wire. Note that these aren’t recommended for actual Ethernet traffic, especially long term…but for basic power/data distribution, RJ45’s are great!
