Würth Elektronik Coax Connectors

Würth Elektronik Coax Connectors contain a wide range of standard SMA solutions for frequencies up to 27GHz. These SMA connectors include WR-SMA, WR-RPSMA, WR-SMB, WR-SMP, WR-ADPT, WR-CXASY, and WR-UMRF types. The WR-SMA and WR-RPSMA series are standard or reverse polarity subminiature version A connectors that include panel-mounted versions with solder cups, flat tabs, or round post connections. 

WR-SMB subminiature coaxial connectors are suitable for applications up to 4GHz and are designed with a snap-on coupling feature. The WR-SMP series features SMP miniature connectors with slide-in and snap-on functions, providing a fully compatible interconnect application up to 18GHz. The WR-ADPT series offers a full range of adapters: Plug-Jack, Plug-Plug, or Jack-Jack in both SMA and reversed polarity SMA. The WR-CXASY cable assemblies provide a variety of pre-assembled SMA assemblies. Würth Electronics Coax Connectors are ideal for telecommunication, automation, and industrial machine-to-machine communication applications.

WR-UMRF RF Coaxial Connectors are ultra-miniature, feature a 3mm x 3.1mm footprint, 2.5mm mating height, and are designed with snap-on mating, allowing for a fast and convenient connection.

Products by Category

  • WR-SMB
    Snap-on coupling feature is suitable for applications up to 4GHz. Smaller than the SMA series and ideally suited for circuit miniaturization.
  • WR-SMP
    Slide-in and snap-on functions provide a fully compatible interconnect application up to 18GHz. The interface is in accordance with MIL-STD-348.
  • WR-SMA
    Designed with threaded coupling technology to ensure high mechanical stability and the bridge between RF and microwave frequencies. 
  • WR-ADPT
    Provides different SMA adaptors for users to change the interface between the plug, jack, and reverse polarities.
  • WR-CXASY
    Offers a variety of pre-assembled cable assemblies for SMA plug to SMA plug and SMA plug to SMA bulkhead jack in different cable types. Flexible cables are available from RG58, RG142, RG174, RG316, to RG316 double braid.
  • WR-UMRF
    Expands the Würth Elektronik coaxial connector portfolio. This series is available in plug and jacks, cable assemblies (jumper and antenna cables), adapters (SMA jack/Plug to UMRF jack), and manual tools for insertion and extraction.
  • WR-RPSMA
    Reverse Polarity SMA connectors are in inverse design to standard SMA connectors for polarization, according to FCC regulations for Antenna requirements.
