Honeywell Dolphin CT40 Mobile Computer Headphone Jack's Product Operating Principle



  1. A standard 3.5mm plug is inserted, making a secure physical and electrical connection with the internal spring-loaded contacts.

  2. The contacts apply a consistent operating force (3~30N) to the plug, ensuring a stable audio signal transfer without interruption.

  3. Upon removal of the plug, the contacts disengage and return to their original position, ready for the next insertion cycle.
