HRM-101S(09) Connectors, Interconnects

Coaxial connectors are designed for use in a wide variety of applications, particularly in radio frequency (RF) fields. One particularly noteworthy application is the HRM-101S(09) connector. This article briefly introduces the application field and working principle of the HRM-101S(09) connector.

Scope of Application of HRM-101S(09)

HRM-101S(09) connectors are military grade COTS connectors (commercial off-the-shelf connectors) that have been approved by the DoD for military, commercial, and industrial applications. The connectors conform to the military’s MIL-PRF-31090/32205 specification and are made of a multiplicity of metal and non-metal materials, depending on the application.

The connectors feature robust, superior electrical and mechanical performance at frequencies up to 20 GHz. Construction features of the connectors include an interference tube design and controlled dielectric extension to maintain high levels of signal integrity. It is ideal for various wiring and cabling applications.

Working Principle of HRM-101S(09)

The HRM-101S(09) connector is a type of coaxial connector. Coaxial connectors have an inner conductor surrounded by an outer conductor and a dielectric to separate the two. Electrical signals pass through the inner conductor, while the outer conductor acts as a shield to protect the inner conductor from interference. The dielectric is used to maintain the correct spacing between the two conductors.

The HRM-101S(09) connector has a unique construction that allows for a high level of signal integrity. The dielectric is composed of multiple isotropic layers that are arranged in a concentric fashion. This increases surface area and capacitance, reducing signal loss. Additionally, the inner conductor is press-fitted into the dielectric and is specially treated to ensure smooth signal transmission with minimal reflections.

The HRM-101S(09) connector also features shaped contacts that reduce insertion and return loss. The contacts are made of corrosion-resistant gold, making them suitable for use in harsh environments and humid climates. The connector also has a unique locking mechanism that provides a secure connection.

Conclusion

The HRM-101S(09) connector is a military-grade COTS connector that has been approved for commercial and industrial applications. The connector features an unique interference tube design and controlled dielectric extension, which ensures superior signal integrity, even at frequencies up to 20 GHz. Additionally, the connector has shaped contacts that reduce insertion and return loss, and a unique locking mechanism for an secure connection. These features together make the HRM-101S(09) an ideal choice for wired and cabling applications.
