Developed in 1986, the 2.4 mm connector is a 50 ohm screw-on precision connector designed for operation up to 50 GHz. The 2.4 mm connectors are standardized according to IEC 61169-40 and are used in a wide range of applications including satellites, test & measurement, and radars. The connectors are mechanically compatible with 1.85 mm connectors. They look similar to the SMA and 3.5 mm connectors but cannot mate with SMA, 3.5mm and 2.92mm without the use of precision adapters.

2.4 mm connectors are more robust than traditional SMA and 2.9 mm connectors and have a thick outer conductor, which increases the outer wall thickness and strengthens the female fingers. The thicker wall of the connector body is designed to engage prior to the center conductor creating a more ruggedized and repeatable mating interface. The interface is air dielectric with the contact supported by a short dielectric bead. 

Key Features:

  • Operation from DC to 50 GHz
  • Impedance: 50 Ohm
