BMA Male Straight 2-hole Flange Brass RF Coaxial Connector for PCB
Mount
The BMA series connector is a blind mate connector developed and
manufactured in accordance with the IEC1169-33 standard. It
features a novel spring plate structure that ensures reliable
contact and superior electrical performance. This connector offers
the advantage of being able to float both axially and radially,
with minimal space between each connection point and a lightweight
design, making it suitable for use in chassis cabinet blind mate
applications. The BMA series is widely utilized in module
connections for chassis cabinets. These connectors are
interchangeable with international counterparts, allowing for quick
engagement and disengagement, and are commonly used to connect
coaxial cables in radio equipment and instruments.

Features:
1. Good mechanical properties: small size and light weight, easy to
use in equipment with limited space. Adopting the new design of
blind mating, it can realize fast and safe plugging and unplugging,
which is suitable for applications with frequent connection and
disconnection, such as telecommunication infrastructures, radar
systems, etc., and can effectively improve the efficiency of the
use of the equipment and the convenience of maintenance.
2. Reasonable structural design: Structurally it is the push-in
form of SMA series, and the interface interface adopts air
interface, this design helps to reduce the size and weight of the
connector, while maintaining good electrical performance.
3. High reliability: with a high mechanical life, generally up to
500 times or more, can ensure stability and reliability in the
long-term use of the process.
4.Wide range of application: suitable for a variety of microwave
circuit connections, especially for chassis, cabinets, blind
insertion and closure, conducive to the modularity of the radar and
other complete systems, has been widely used at home and abroad.
Application:
1. Aerospace: in aircraft, satellites and other aerospace
equipment, used to connect a variety of electronic equipment and
communication systems, such as satellite communication antennas,
airborne radar, electronic warfare systems, etc. The
miniaturization and lightweight characteristics of BMA connectors
are conducive to reducing the weight of aerospace equipment, and
improving the portability and mobility of the equipment; at the
same time, their high reliability and seismicity, to adapt to the
harsh conditions of aerospace environment.
2. Test and Measurement Instruments: In RF test instruments, such
as spectrum analyzers, network analyzers, signal generators, etc.,
they are used to connect the RF signal transmission between the
equipment under test and the test instruments. Its precise
electrical performance and stable connection characteristics can
ensure the accuracy and reliability of test results and help
improve the efficiency and precision of test and measurement.
