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.
