SMPM (SubMiniature Push-on Micro) sealed connector is a miniaturized RF connector with full escapement, semi-escapement, and light hole, designed for high frequency, compact space, and lightweight applications. It is a push-on connector, commonly used in communications and electronic equipment that require low weight, high reliability, and small size. SMPM connectors have high signal transmission quality and can provide good electrical performance.
Basic structure:
SMPM-J type air-sealed RF coaxial connector consists of three parts: outer conductor, glass medium and inner conductor, the basic structure is shown in the figure below:

Interface Size:
SMPM-J type air-sealed RF coaxial connectors have two interface forms: full escapement and bare hole. When model naming, F indicates full escapement and
S means light hole. The interface dimensions are divided into standard interface dimensions and short interface dimensions, both of which are intermateable with SMPM-K type plugs.
Standard interface size:
