female mmcx connector for Westone earphone

Type MMCX RF coaxial Connector is a Kind of miniature Connectors smaller than type MCX.

Characteristic impedance is 50Ω. The characteristic of connectors is in small volume, light weight, Convenient

Connection and reliable. They are widely used in connect with the RF coaxial cables, transmission of RF signal,

equipments or small-sized communications network that are demanding on systematic volume and weight. By

using surface mounting technology,It is suitable for mass instrument equipment production and producing on the assemly line.
