Micro USB to RJ9 4P4C adapter cable

This 0.25 metre adapter cable bridges a microUSB male connector to an RJ9 4P4C male plug for telephone handsets, headsets and custom DIY hardware projects. It provides direct signal conversion between the two interface standards without requiring drivers or configuration.

Check pin assignment before ordering

Verify that your device pin definition matches this cable because wrong pin assignment may cause abnormal function or no signal output. The cable is designed for signal transfer scenarios and is not suitable for high current power supply applications.

Compact 25 cm length with flexible shielding

The short 25 centimetre length avoids redundant cable clutter inside equipment cabinets or small space installations. Flexible outer shielding material improves tensile strength and anti interference performance for steady signal transmission during frequent plug and removal cycles.

Questions about this item

Does the package include any drivers or software for the Micro USB to RJ9 adapter?

No drivers or software are required; the 0.25M cable is a passive plug-and-play converter.

Should I choose a longer cable than the 25 centimetre version for a desktop headset?

The 25 centimetre length is designed for compact installations; select a longer cable only if the devices are farther apart.

Will the 0.25M converter power a telephone handset from the USB port?

The adapter is intended for signal transfer only and is not designed for high-current power supply applications.
