PJ-3215A: Horizontal SMT 3.5mm Audio Jack

TSI Incorporated VelociCalc 9565 Headphone Jack's Product Operating Principle

1. A 3.5mm plug is inserted, causing internal spring contacts to physically engage with the plug's tip, ring, and sleeve sections.

2. This engagement establishes distinct electrical pathways for audio channels (e.g., left, right) and a common ground connection.

3. The SMT leads provide a secure solder connection to the PCB, ensuring stable signal transfer from the jack to the device's circuitry.
