Board-to-board connections

Today’s energy metering, measuring and controlling devices are often built from several modules, boards or building blocks. This is mainly done to increase flexibility and for the easy customisation of products, which is often required due to legal differences in countries or differences in standards applying to operators or countries.

Since most devices have wireless or cellular connectivity, or required transmission of high data rates between boards, a highly flexible and low cost solution for transmitting RF signals between boards and/or building blocks is required.

Eliminating cabling to reduce costs is common in today’s industry. This may however increase mechanical stress significantly, especially since in most cases a solution for a mechanical overdetermined system needs to be provided. To overcome this, whilst continuing to maintain excellent electrical properties, board-to-board connectors need to be employed.

HUBER+SUHNER offers different board-to-board solutions (MMBX, MFBX and MBX) allowing board-to-board, board-to-panel, and board-to-board-through-panel connectivity. This technology brings features such as blind-mateability and large axial and radial working ranges.

RF cables (specialities)

Some products cannot be allocated in any of the three main lines. They are consolidated in the speciality cable line. It includes special designs like odd impedance, twinax or triax cables. A selection of low-noise coax and triax cables is also available. Cables with special qualification, for instance in accordance with railway norms like EN 45545 or in accordance with UL are also listed in this section.

Low noise coax and triax cables

HUBER+SUHNER low noise coax and low noise triax cables are developed for sophisticated signal measurements. The low noise technology with semi-conductive layer for the transmission of weak analogue sensor signals, mostly of high impedance, are used in various applications.

Triax cables

HUBER+SUHNER triax cables consist of an additional outer conductor which is usually used for power supply or grounding purposes of any devices. Apart from that, the extra outer conductor represents a second shielding layer and increases the shielding effectiveness.

Board-to-board connectors

HUBER+SUHNER MBX/MFBX/MMBX connectors are especially developed for board-to-board and board-to-module RF interconnections. The mechanical design is outstanding, allowing the MBX/MFBX/MMBX to cope with mechanical misalignment in radial and axial directions and still hold an excellent electrical performance. These series are the answer to higher integration and miniaturisation. They are the perfect solution for multiple connections from board-to-board and complex stack-ups in radio module applications.

Contact-Bridge

HUBER+SUHNER Contact-bridge is a fully integrated horizontal board-to-board connection. The product consists of a centre pin (sheet metal) and the dielectric (plastic molded). The Contact-bridge is assembled into a based plate whereas the base plate is then also the outer contact (ground). The size of modules can be further reduced with the Contact-bridge as a fully integrated solution. This product can be used for various connections from board-to-board like RF, signal or power.

MBX

HUBER+SUHNER MBX connectors are especially developed for board-to-board and board-to-module RF interconnections. The mechanical design is outstanding, allowing the MBX to cope with mechanical misalignment in radial and axial directions and still hold an excellent electrical performance. MBX completes together with the MBX 2nd generation the board-to-board assortment of HUBER+SUHNER with its development based on the well-known board-to-board connector MMBX. MBX fulfils higher requirements with best in class axial misalignment of ±1.2 mm. MBX is the answer to higher integration and miniaturisation. It is the perfect solution for multiple connections from board-to-board / board-to-module and complex stack-ups in radio module applications.

MBX 2nd generation

Together with the standard MBX, the new MBX 2nd generation is the first choice in board-to-board connections. The MBX 2nd generation board-to-board connection comes along with the well-known and outstanding characteristics of MBX but optimised plating, materials and production process.

MFBX

HUBER+SUHNER MFBX and eMFBX connectors are especially developed for high-volume PCB-to-PCB applications. MFBX / eMFBX connectors are tailor-made solutions for medium axial and radial misalignments requirements at frequencies up to 6 GHz. MFBX connectors are based on machining technologies whereas eMFBX is based on stamp and bending.

MMBX

HUBER+SUHNER MMBX connectors are especially developed for board-to-board and board-to-module RF interconnections. Along with MBX the board-to-board portfolio of HUBER+SUHNER provides highest flexibility for today´s and future radio module applications. MMBX connectors offer an operation frequency up to 12.4 GHz. The series contains of a wide range of board and cable connectors with a minimum board-to-board distance of only 6.7 mm.
