2.5 mm female jack

Zebra TC52 Headphone Jack's Product Operating Principle

Mechanical Engagement & Alignment: Upon insertion, a standard 2.5mm audio plug precisely engages with the jack's internal spring-loaded contacts. The specified operating force (3-30N) ensures a secure mating, preventing accidental disconnection while providing a firm tactile response.

Electrical Circuit Completion: The physical contact between the plug's conductive surfaces and the jack's terminals completes the electrical circuit. This allows for the reliable transmission of analog audio signals from the external device to the PCB with minimal signal loss, thanks to a low contact resistance of under 50mΩ.

Secure PCB Integration: As a Surface Mount Technology (SMT) component, the PJ-223 is designed to be soldered directly onto the surface of a Printed Circuit Board (PCB). This horizontal mounting provides a strong mechanical bond and a low-profile integration, critical for automated reflow soldering and compact product designs.

Interacoustics AD629 Headphone Jack's Product Functions

High-Fidelity Audio Interface: Delivers a stable and clear connection for transmitting analog audio signals. It acts as the primary port for headphones, microphones, or external audio sources, ensuring excellent signal integrity for a quality user experience.

Enable Device Miniaturization: With its ultra-compact footprint (12.00mm x 7.00mm) and low height (3.20mm), this jack allows engineers to design smaller, thinner, and more portable electronic devices without compromising on connectivity.

Streamline High-Volume Manufacturing: The SMT and tape-and-reel packaging design is fully compatible with automated pick-and-place machinery and reflow soldering processes. This drastically reduces assembly time and labor costs, enabling efficient mass production.

Guarantee Long-Term Reliability: Engineered for durability, it withstands a minimum of 5,000 insertion/extraction cycles. Its robust build and high dielectric strength (AC 500V) ensure consistent performance and safety over the product's entire lifespan, even in demanding applications.

Philips VoiceTracer DVT1120 Headphone Jack's Product Applications

Industrial & Commercial Devices:

Example: Perfectly suited for the push-to-talk (PTT) headset port on rugged mobile computers like the Zebra TC52 or two-way radios like the Motorola TLK 100. 

It enables clear, hands-free communication for logistics, retail, and field service personnel in noisy work environments.

Medical Equipment:

Example: Can serve as the critical audio port in diagnostic equipment, such as the examiner’s headphone jack on a portable audiometer like the Interacoustics AD629. 

This provides a reliable connection essential for accurate hearing tests and patient diagnostics.

Consumer & Domestic Electronics:

Example: Is the ideal component for the external microphone or headphone jack in compact devices like the Philips VoiceTracer DVT1120 digital recorder. 

Its small SMT profile is essential for achieving the slim, portable design that consumers demand.
