The SMA connector range offers semi-precision performance with a 50-ohm impedance and a 0.25 - 36 threaded coupling. These compact Sub Miniature version A connectors are frequently used as a standard for antennas, devices, and various medical applications. They are also known as F type coaxial connectors. Designed for relatively small electronic equipment, these connectors typically support up to 500 mating cycles, provided mating surfaces are kept clean.
