PJ-3214 | 3.5mm Horizontal SMT Earphone Jack

Kestrel 5500 Weather Meter. Headphone Jack's Product Operating Principle

1. When a 3.5mm plug is inserted, its conductive surfaces (tip, ring, sleeve) make firm contact with the jack's internal spring terminals.

2. These contacts establish distinct electrical pathways, reliably transferring left audio, right audio, and ground signals from the PCB.

3. The SMT design ensures a secure, low-profile connection directly to the circuit board, minimizing signal loss and physical strain.

Teenage Engineering OP-1 Field Headphone Jack's Product Functions

1. Provides a standard universal interface for connecting headphones, earphones, and other external audio devices.

2. Enables high-fidelity stereo audio output from an electronic device's main printed circuit board (PCB).

3. Supports audio input capabilities when used in TRRS configurations for devices with integrated microphones.

4. Its SMT design facilitates efficient, automated assembly onto PCBs, reducing manufacturing time and cost.

Grason-Stadler AudioScreener+ Headphone Jack's Product Applications

1. Industrial Automation: Utilized in handheld diagnostic tools for audio alerts or data output, such as the headphone port on a Kestrel 5500 Weather Meter.

2. Professional Audio: Integrated into portable synthesizers and music production gear for headphone monitoring, as seen on the Teenage Engineering OP-1 Field.

3. Medical Devices: Essential in portable diagnostic equipment for private audio feedback, like the operator's 3.5 mm earphone jack on a Grason-Stadler AudioScreener+.
