3.5mm SMT Horizontal Audio Socket | Model: PJ-3277

Pioneer DJ DDJ-200 Smart DJ Controller Headphone Jack's Product Operating Principle

1. A 3.5mm plug insertion aligns with the internal spring contacts, completing the audio circuit path for signal transmission.

2. The jack's SMT terminals are configured to transfer stereo (L/R) and ground signals from the plug to the printed circuit board.

3. Low contact resistance (50mΩ Max) and high dielectric strength (AC 500V) ensure a pure, interference-free audio signal.
