Connector
Description：
The SBMA series is a miniaturized BMA connector consisting of a blind mate connector with fixed and floating contacts; it can be adjusted for a certain amount of axial and radial misalignment. The in-line connection mechanism saves rotational space and increases packing density compared to threaded connection mechanisms. SBMA connectors are suitable for applications where multiple connector contacts are required, especially for subsystems and system “blind-mate” interconnections. This series of products can be customized according to customer requirements.
Application:
Widely used in radar and other complete systems.
Features:
- Small size and high reliability
- Easy maintenance
- High degree of standardization
