New High Performance & Robust BMR-Spring Board-to-Board Connectors

As the exclusive distributor of Radiall products, Rojone is proud to introduce the addition of new high-performance and robust BMR-Spring large misalignment board-to-board connectors to their extensive offering of cost-effective subminiature RF coaxial solutions.

Radiall BMR-Spring connectors can handle a minimum board-to-board or rack and panel distance tolerance of at least 0.078” (2 mm) with custom misalignment of 3 mm or more.  It also features a 6 degree tilt radial travel.   It has an operating frequency range of DC-8 GHz, a 1.1 max VSWR guaranteed up to 3 GHz, and it can handle up to 350 watts of power at 2.7 GHz.

The Radiall BMR-Spring adapter features a unique non slotted spherical interface for improved electrical performance, high vibration and shock resistance, and an 80dB of shielding up to 3 GHz.  A self-alignment mechanism makes the BMR-Spring particularly ruggedized for blind-mate applications.  The spring-loaded adapters are symmetrical to avoid any assembly issues.

A typical BMR-Spring board-to-board system is made of three parts – slide-on receptacle, symmetrical adapter and snap-on receptacle.  Custom configurations are also available for board-to-board, module-to-module, or rack and panel applications.
