Datalogic Skorpio X5 Headphone Jack's Product Operating Principle



  1. A standard 3.5mm 4-pole (TRRS) male plug is inserted, connecting with four internal contacts for stereo audio, microphone, and ground signals.

  2. The SMT (Surface Mount Technology) design allows the jack to be soldered directly onto the surface of a printed circuit board for a secure, low-profile fit.

  3. Four independent electrical conductors ensure clear, stable transmission for stereo audio output and a dedicated microphone input channel.


Nonin Avant 9600 Headphone Jack's Product Functions



  1. Provides a universal I/O port for devices requiring both stereo audio output and microphone input, such as headsets.

  2. The compact (11.80*6.50mm) horizontal design saves valuable space in slim or high-density electronic devices.

  3. Engineered for automated manufacturing, its SMT-compatibility streamlines the PCB assembly process.

  4. Offers robust connectivity with a low contact resistance (50mΩ Max) for superior signal integrity.
