2.92mm

The 2.92mm connector has a male pin shorter than an SMA or 3.5mm interface to ensure outer contacts engagement before the pin and female receptacle mate. This design feature minimizes wear and mating stress seen by misalignment in an SMA or 3.5mm connector. The 2.92mm connector also has a thicker wall than a standard SMA. The 2.92mm series mates with SMA and 3.5mm connectors.
