HN Coaxial Connector

The HN (High Voltage N) coaxial connector is a heavy-duty, 50Ω RF interface engineered for ultra-high voltage applications exceeding SHV capabilities. Defined by MIL-C-39012/16 and IEC 60370, it features an extended threaded coupling mechanism and significantly increased creepage/clearance distances compared to standard N-type or SHV connectors. Designed for continuous operation up to 15 kV RMS (sea level), the HN provides robust environmental sealing, superior mechanical strength, and reliable arc suppression in demanding industrial, scientific, and defense high-voltage systems where safety margins are non-negotiable.

Safety & Handling Warnings

• Never mate/unmate under load. HN connectors lack hot-plug safety interlocks. Always de-energize and verify zero voltage before handling.
• Torque control is mandatory. Over-torquing cracks ceramic/PTFE dielectrics; under-torquing causes arcing at threads. Use calibrated torque wrench (typically 15–20 in-lbs).
• Inspect thread integrity. Cross-threading or galling compromises shielding and voltage rating. Reject connectors with damaged threads immediately.
• Use only matched HN-to-HN interfaces. Adapters to N/SHV reduce voltage rating to lowest component spec. Verify adapter certification for target voltage.
• Verificatio de connexionis ad terram requiritur. Confirmare continuitatem ad terram chassidis antequam energizetur. Terrae flottantes causant defectum catastrophalem isolationis.
