Product Overview
The model of SSMA female connector is SSMA-C-K1.5.SSMA series are 50 ohms screw coupling subminiature coaxial connectors. With the characteristics of small size, light weight, wide frequency range and high reliability, they are widely used in applications where size and weight are critical,such as high accuracy miniaturized mobile electrical instruments, network,and connected to RF cables to transmit RF signals. In assembly of high accuracy semi-flexible cable,SSMA can work up to 18GHn or higher.


Specifications and Dimensions
1. Interface Dimensions
The interface dimensions of an SSMA connector primarily include key parameters such as the inner conductor diameter, outer conductor diameter, and contact length. Generally speaking, the inner conductor diameter of an SSMA connector is relatively small, typically ranging from 0.028-0.040 inches (0.71-1.02 mm); the outer conductor diameter is also correspondingly smaller, typically around 0.118 inches (3.00 mm). This design helps reduce the size and weight of the connector and improve its high-frequency performance.
2. Overall Dimensions
In addition to the interface dimensions, the overall dimensions of an SSMA connector are also a key concern for users. Overall dimensions include parameters such as connector length, width, and height. Specifically, the length of an SSMA connector typically ranges from 0.5-1.0 inches (12.7-25.4 mm), while the width and height vary depending on the product design. When selecting an SSMA connector, users should determine the appropriate overall dimensions based on the actual application scenario and requirements.
