SMA connectors are a mainstay of low frequency wireless technologies.

This bulkhead mounted SMA Female connector is designed for an ordinary crimp and solder attachment to LMR-240 and equivalent series coaxial cables.

Installation is simple. After preparing the cable, the pin is soldered onto the centre conductor and outer body pushed over the top until the pin sits flush. A standard 6.5 mm (0.255") hex die is used to crimp the ferrule.

The bulkhead interface allows the SMA connector to be panel mounted by drilling a 7 mm diameter hole and sliding the body from the rear through the hole. The supplied nut and washer secures the SMA connector to the mounting surface.
