3.5 headphone jack

Focusrite Scarlett 2i2 Headphone Jack's Product Operating Principle

1. A standard 3.5mm plug is inserted, making secure physical contact with the internal terminals to complete the audio signal circuit.

2. The jack's conductive paths efficiently transfer left, right, and ground audio channels from the PCB to the connected device.

3. As an SMT component, it is placed on PCB solder pads and permanently bonded during the reflow soldering process for a strong connection.
