Würth Elektronik WR-UMRF coaxial connector

The WR-UMRF (Ultra-Miniature RF Coaxial Connector) is a compact, high-frequency coaxial connector from Würth Elektronik. The plug snaps into the jack to form a stable, right-angled, cable-to-board connection with a height of just 2.5 mm; this connection technology is particularly useful for connecting antennas to radio modules. The frequency range extends up to 6 GHz at 50Ω.

With its low height of 2.5 mm, the product is a slim connection solution and also only requires a footprint of just 3.1 x 3 mm for PCB mounting. In terms of technical specifications, it is compatible with many similar products on the market. Würth Elektronik also offers pre-assembled cables with various combinations of UMRF, SMA or RP-SMA — optionally with protection class IP67. The available cable diameters are 1.13, 1.32 and 1.37 mm.
