HN vs N: Specifications, Key Differences, and Selection Guide
HN and N connectors share a similar threaded coupling design, but they are built for different electrical requirements.
N connectors are the industry standard for general RF signal transmission, while HN connectors are specifically designed for high-voltage and high-power applications with enhanced insulation.
Although they look similar, HN and N connectors are not mechanically compatible and should never be connected together.
Quick Summary
・Purpose: N – General RF transmission / HN – High-voltage RF transmission
・Coupling: Both use threaded coupling
・Voltage: HN supports much higher voltage
・Size: HN is larger with extended insulation
・Compatibility: Never interchangeable
What Are HN Connectors?
HN (High-voltage N) connectors are RF coaxial connectors designed for applications requiring high voltage, high power, and reliable insulation.
Although their threaded interface resembles the standard N connector, HN connectors feature a larger body and extended dielectric structure to safely handle higher voltages.
Typical applications include high-voltage power supplies, semiconductor equipment, laboratory instruments, radiation detection systems, and industrial testing equipment.
Specifications
・Impedance: 50 Ohm
・Coupling: Threaded
・Rated Voltage: Up to 1.5 kV
・Typical Use: High-voltage equipment
What Are N Connectors?
N connectors are one of the most widely used RF coaxial connectors for medium- to high-frequency signal transmission.
Their threaded coupling provides a secure and vibration-resistant connection, making them ideal for communication equipment, measurement systems, antennas, and outdoor RF installations.
N connectors are available in both 50 Ohm and 75 Ohm versions depending on the application.
Specifications
・Impedance: 50 Ohm / 75 Ohm
・Coupling: Threaded
・Typical Use: RF communication

Key Differences Explained
1. Voltage Capability
The biggest difference is voltage handling.
HN connectors are specifically engineered for high-voltage applications with reinforced insulation, while N connectors are intended for conventional RF signal transmission.
2. Insulation Design
HN connectors include an extended dielectric structure that increases electrical clearance and improves insulation performance.
This design helps prevent electrical breakdown when handling high voltage.
3. Connector Size
HN connectors are physically larger than N connectors.
The larger dimensions allow for thicker insulation while maintaining reliable RF performance.
4. Typical Applications
HN
・High-voltage power supplies
・Semiconductor equipment
・Radiation detectors
・Laboratory instruments
・Industrial testing
N
・RF communication
・Wireless infrastructure
・Antennas
・Test equipment
・Broadcast systems
Are HN and N Compatible?
No.
Although both connectors use threaded coupling and have a similar appearance, they have different internal dimensions and insulation structures.
HN connectors include extended insulation that prevents them from mating with standard N connectors.
Attempting to connect them may damage the connector or create an unsafe electrical connection.
