Blind Mate Connectors

Coaxial Connectors are one of the key components in high-frequency communication and RF technology applications. They are in charge of transmitting signals and ensuring the stability of electrical performance. The internal circuit modules of equipment between modules in 5G communication equipment modules, radar equipment modules and other terminal equipment need to carry out multi-channel simultaneous insertion and use, in order to quickly install and remove. At the moment blind mate connectors is the best choice for use. The current blind mate connectors’ types are SMP, SSMP (SMPM), BMA, BMAM and other series. Due to the limited space of the module structure, these blind mate connectors will satisfy the space and miniaturization needs. However, because of the blind mate connectors of different series are designed by different interface, the selection of the appropriate blind mate connectors is the best choice for use as well as will improve the connection efficiency.

What is an RF Blind mate connector?

Blind mate connectors as a special type of connectors, are widely used in many industrial and commercial applications due to their unique features of automatic alignment and fast connection. Blind mate connectors do not require precise manual alignment. The user simply inserts the connector into the corresponding port and the connection between modules is automatically made. These features make them ideal for applications where space is at a premium or they are difficult to shift, and can greatly improve connection efficiency and reduce handling time.

Blind mate connectors are designed to be used without visual assistance or precise alignment. They allow connections to be made automatically where direct vision or manual alignment is not possible. Blind mate connectors are designed to be particularly suitable for applications where space is limited or the connection is difficult to reach, such as in aerospace, military and communications equipment.

There are several factors to consider when choosing the right blind mate connectors

Frequency Range

Select the supported frequency range according to the application requirements. Such as SMP support up to 40 GHz, which is suitable for high-frequency applications. The frequencies are listed in descending order as SSMP (65 GHz) > SMP (40 GHz) > BMAM (28 GHz) > BMA (22 GHz).
 

Plugging and Un-plugging Frequency

The plugging and unplugging durability of the connector needs to be considered to ensure long-term use without compromising performance.
 

Size and Density

Select the appropriate size according to the space and design density requirements, e.g. SSMP is more suitable for high-density applications. The external dimensions are ranked from largest to smallest as BMA>BMAM>SMP>SSMP.
 

Installation Environment

For applications in harsh environments such as military or aerospace would be more suitable to choose a durable type such as BMA connector.
 

Applications of Blind Mate Connectors
