3.5mm SMT Horizontal Audio Phone Jack – Model: PJ-3288B

Omega Engineering HHTQ31 Torque Meter Headphone Jack's Product Operating Principle

1. When a 3.5mm plug is inserted, internal spring contacts securely connect with the plug's tip (left audio), ring (right audio), and sleeve (ground).

2. The jack establishes three distinct electrical pathways, reliably transferring analog stereo audio signals from the PCB to the connected output device.

3. A consistent operating force (3-30N) ensures a stable connection and tactile feedback, protecting against accidental disconnection during use.
