Coaxial Connectors (RF) are widely used in a diverse range of applications including telecommunications, broadcasting, military, high-speed data transmission, and consumer electronics. The M39012/56B3117 is a two-piece medium power crimp style RF connector from the Glenair family of coaxial connectors. It is specifically designed to provide reliable connections in harsh environments. It has an operating voltage rating of 500V and a maximum continuous operating current rating of 13A. The M39012/56B3117 is commonly used in avionics, instrumentation, and radar systems.

The M39012/56B3117 has a robust construction with the center contact being made of a beryllium copper alloy material. The interior surfaces of the center contact are gold-plated to ensure a reliable contact with the mating center contact. The rear section of the contact is constructed from a high-grade plastic dielectric material that insulates the contact from the outer shell. The contact is thena ctually soldered to the center conductor of the coax cable.

The outer shell of the M39012/56B3117 is composed of a lightweight aluminum alloy. It provides a continuous 360-degree shield connection with the mating center contact and has a nitrile rubber O-ring for a positive seal against environmental contaminants. This shell is also fabricated with a flared rim to ensure secure attachment of the crimp ferrule.

The crimp ferrule of the M39012/56B3117 is constructed from zinc-plated steel and is designed to provide a reliable mechanical and electrical connection between the coax cable and the connector. It is fitted with a sacrificial tube to prevent over-crimping and contact damage during installation. The ferrule is attached to the coax cable by tightening a threaded collar, which compresses the ferrule to the cable jacket under pressure, ensuring a solid mechanical connection.

The operating principle of the M39012/56B3117 is based on the principle of electromagnetic compatibility (EMC). The center contact of the connector, which is soldered to the center conductor of the coaxial cable, provides an electrical connection between the center contact of the mating connector and the center conductor of the cable. The outer shell of the connector is then designed to provide a 360-degree shield connection between the outer shell of the mating connector and the outer conductor of the coaxial cable. This ensures that the electrical connection between the two components is maintained and electromagnetic interference is blocked.

The M39012/56B3117 is a reliable two-piece medium power crimp-style RF connector from Glenair. It is designed to provide a reliable connection in harsh environments and is commonly used in avionics, instrumentation, and radar applications. Its operating principle is based on the principle of electromagnetic compatibility and provides an electrical connection between two components as well as an effective shielding to block electromagnetic interference. This connector is an easy to install and cost-effective solution for a variety of applications.
