Würth Elektronik has introduced additional coaxial connectors for 50 Ω cables of types 1,13, 1,32, and 1,37 mm. The plugs and receptacles, suitable for use in such equipment as wireless communication devices, GPS systems, and IoT devices, feature gold-plated contacts and have all passed a 48-hour salt spray test. The easy-to-install connectors WR-SMA, WR-SMB, WR-MCX and WR-MMCX are now available from stock.

The WR-SMA is a right-angle bulkhead jack cable connector for applications up to 6 GHz that features a very space-saving design and reduced cable strain. The new model in the WR-SMA series for crimp assembly is also available in an IP67-rated version.
The WR-SMB is a straight plug cable connector similar in size to the SMA version, but is straight and features a snap-lock mechanism. The connector, for applications up to 4 GHz, is particularly suitable for applications such as test equipment that require repeated mating cycles.
The WR-MCX straight and right-angle plug cable connectors feature a snap-lock mechanism and are suitable for applications up to 6 GHz. The connectors take up very little space and remain rotatable, which provides added flexibility for the right-angle plug connectors. These connectors have been tested for at least 500 mating cycles. The WR-MCX has a connector diameter of 4,5 mm, while the WR-MMCX version has an even smaller diameter of just 3,5 mm. The smaller connector also requires less force both for mating and unmating.
