Motorola CLP1010e Two-Way Radio Headphone Jack's Product Operating Principle

1. A standard 2.5mm audio plug is inserted, making secure physical and electrical contact with the internal spring-loaded terminals to complete the circuit.

2. The SMT leads, soldered directly to the PCB, reliably transfer analog audio signals from the device's mainboard to the connected headphone or cable.

3. A balanced operating force (3-30N) provides a firm, stable connection while ensuring smooth insertion and removal for an excellent user experience.

SanDisk Sansa Clip Jam Monitor Headphone Jack's Product Functions

1. Provides a standard I/O port for transmitting clear analog audio signals to headphones, earpieces, or external audio equipment.

2. Enables a compact product footprint with its horizontal SMT mounting, saving valuable vertical space on the printed circuit board.

3. Streamlines the manufacturing process with a design fully compatible with high-speed, automated SMT and reflow soldering assembly lines.

4. Ensures high signal integrity with low contact resistance (50mΩ Max) and robust dielectric strength (AC500V) for noise-free performance
