HN RF Connectors Guide
What are HN RF Connectors?
HN RF connectors are coaxial connectors designed for high-voltage and high-power applications. They support rated voltages of up to 15 kV and offer high dielectric strength, making them suitable for demanding electrical environments.
These connectors feature a threaded coupling mechanism similar to N-type connectors, but they are larger and specifically engineered for improved insulation and safety. HN connectors are not compatible with N connectors and cannot be mated together.
Due to their robust construction and high-voltage capability, HN connectors are widely used in power supply systems, test equipment, and industrial applications where reliable high-voltage transmission is required.

HN vs N RF Connectors
HN and N connectors are both threaded RF connectors, but they are designed for different performance requirements.
HN connectors are larger and specifically designed for high-voltage applications, offering improved insulation and higher power handling capability. In contrast, N connectors are more compact and widely used in general RF applications.
While N connectors are suitable for standard RF systems, HN connectors are preferred in high-voltage environments where enhanced safety and performance are required.
High Voltage RF Connectors (HN, MHV, SHV)
High-voltage RF connectors are designed to safely handle elevated voltage levels in specialized applications.
- HN: Suitable for high-power and high-voltage systems, offering robust insulation and high power handling capability.
- MHV: Commonly used in moderate voltage applications where compact size and cost efficiency are important.
- SHV: Designed for higher voltage environments with enhanced safety features to prevent accidental contact.
These connectors are typically used in power supplies, test equipment, and industrial systems where stable high-voltage transmission is required.
Selecting the appropriate connector depends on voltage requirements, safety considerations, and application conditions.

Trivia: Compatible Cable Types
- MIL-Standard Coaxial Cables
These cables, also known as Mil-Spec, are engineered to meet rigorous US military specifications for performance and durability. They often feature the "RG" prefix, which stands for "Radio Guide," reflecting their roots in radio technology. They are critical in demanding applications like defense, aerospace, and telecommunications, where reliability is non-negotiable.
HN RF Connector Features
High Voltage Compatibility
HN RF connectors are specifically designed for high-voltage applications, with a rated voltage of up to 1.5 kV and a withstand voltage capability of up to 5 kV/min. This makes them suitable for use in demanding environments where high voltage stability is critical.
Superior Stability
Unlike Quick-Connect connectors, which are typically faster to engage, the threaded coupling design of HN connectors ensures a more secure and stable connection. This design minimizes the risk of signal loss or disconnection, offering enhanced reliability, particularly in high-vibration or high-stress conditions.
HN RF Connector Applications
HN RF connectors are coaxial connectors designed for high-voltage applications. With a rated voltage of up to 1.5 kV and the ability to withstand up to 5 kV for one minute, they excel in demanding environments. The threaded coupling provides a secure, stable connection. These connectors are ideal for instrumentation, high-voltage test equipment, airframes, and radiation detection equipment.
How to Choose HN RF Connectors
Choosing the right HN RF connector depends on voltage requirements, cable compatibility, and application conditions.
