BMA Female Brass Bulkhead Microstrip RF Coaxial Connector
The BMA series represents a category of blind mate connectors, meticulously crafted in adherence to the IEC1169-33 standard. Distinguished by an innovative spring plate design, these connectors ensure dependable contact and exhibit enhanced electrical properties. A key benefit lies in their capability for both axial and radial floating, coupled with minimal spacing between individual contacts and a lightweight composition, rendering them ideal for application in the blind mating of chassis enclosures.
Widely utilized in modular connections for chassis cabinets, the BMA series boasts interchangeability with international counterparts, facilitating swift engagement and disengagement procedures. These connectors are prevalent in the realm of radio equipment and instrumentation, where they serve to establish reliable connections for coaxial cables.

Features:
1. Connection methods: common welding type, snap type and so on. Welded connection is firm and reliable, suitable for long-term use; snap type is easy to quickly insert and remove, suitable for frequent connection and disconnection of the scene.
2. Holding force: the center pin holding force is better, to ensure that the connector will not be easily loosened or fall off in the process of use, for example, there are BMA connector center pin holding force greater than 20N.
3. Durability: long mechanical life, generally can withstand a minimum of 500 times the number of plugging and unplugging, some high-quality products are more durable.
4. Compact size: BMA connector is a miniature push-in connector, compact size, suitable for equipment with limited space.
Application:
1. Communication field: In communication base station, it is used to connect RF module, antenna and other equipments to realize the transmission of high frequency signal. Its good electrical performance and mechanical stability can ensure stable transmission of communication signals, reduce signal loss and interference, and improve communication quality.
2. Radar system: In the radar system, it can be used to connect the various components of the radar, such as transmitter, receiver, antenna, etc., to realize the transmission of microwave signals. As radar system requires high reliability and stability of signal transmission, BMA female microstrip connector's small size, light weight, good electrical performance and anti-vibration and anti-shock ability enable it to meet the strict requirements of radar system.
