HEX40-AC-90-13-A3-3 circular connectors, which belong to the category of Backhells and Cable Clamps, are typically used in high-frequency wire and cable assemblies for data, signal, and power applications. They are designed to provide robustness and flexible mounting configurations in a variety of applications such as onboard and on-machine harnesses, transmitters, testers, and instrumentation.

This type of connector is typically used in radio and communications equipment, radar systems and control systems that require ultra-low-profile and compact design. They are also used in telecom, military and commercial applications, as well as aerospace and medical applications.

The design of HEX40-AC-90-13-A3-3 circular connectors consists of two circular shells – an inner one and an outer one, which are held together by mechanical fastenings. The shells are designed to fit close together with minimal air gap in order to provide complete shielding and EMC protection. The connectors also feature multiple insertion points for attaching the cable, allowing multiple configurations for cable routing, and a multi-contact socket to accept a range of plug options.

Inner shells are filled with a sealing compound to ensure that there is no contact between the connector shells and the cable insulation. The fastener of the inner shell is designed to secure the cable and the cable clamp is used to ensure correct positioning of the cable along the side of the shell.

The outer shell is designed to protect the inner shell and the connection from external elements and has a reinforced rib on the side to secure the cable clamp and protect the fastener. The outer shell is also provided with a locking flange to secure it against accidental opening.

HEX40-AC-90-13-A3-3 circular connectors typically feature a gold plated contact with contact impedance rating of 0.48 Ohms with voltage rating of 1000V and a temperature rating of -65°C to +275°C. The cable is provided with a rubberized polyurethane marshalling seal that ensures the correct positioning of the cable along the outside of the connector shell. The connectors are also provided with metal strain relief to prevent tension from being applied to the active contacts.

HEX40-AC-90-13-A3-3 circular connectors’ working principle is based on completing an electrical circuit through the connection of two circular shells. By connecting the two shells, the contact impedance is reduced to an acceptable level, allowing an electrical current to pass through safely. The contacts are designed to provide vibration and shock resistance, along with EMI protection, by using a combination of shield pins, flexible grommets and other contact options.
