HN RF Connectors Guide
What are HN RF Connectors?
HN RF connectors are coaxial connectors designed for high voltage equipment, with a rated voltage of up to 1.5 kV and a withstand voltage of up to 5 kV/min. They feature a threaded coupling with a mating part similar to the N RF connector, but they are not interchangeable and cannot be mated with N RF connectors.
The name "HN" comes from the similarity of the mating part to the N RF connector, and the connector is suitable for high voltage applications.

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.

HN RF Connector FAQs
QCan HN be mated with N connectors?
QCan HN be mated with N connectors?
Although HN connectors are a threaded coupling type, they are not compatible with N, N75 Ω, or S connectors. They cannot be mated due to the HN connector's extended insulation.
QWhat does the "HN" in HN connector signify?
QWhat does the "HN" in HN connector signify?
The name "HN" is derived from the connector's mating part, which is physically similar to that of the more common N RF connector, but it is not the same.
QWhat are the voltage ratings of HN connectors?
QWhat are the voltage ratings of HN connectors?
HN connectors are designed for high-voltage applications. They have a rated voltage of up to 1.5 kV and a withstand voltage of up to 5 kV per minute for reliability.
QAre HN connectors and N connectors interchangeable?
QAre HN connectors and N connectors interchangeable?
No, HN connectors and N connectors are not interchangeable. While they may appear similar, they have different internal dimensions and therefore cannot be properly mated together.
