Description
The HN (High-Voltage N) series is a specialized RF interface developed for applications where standard N-type connectors would fail due to voltage breakdown. While the HN interface is traditionally 50-Ohm, this variant is optimized for RG59 coaxial cable, frequently used in high-voltage pulse applications, specialized medical equipment, and older high-power broadcasting systems. The HN interface features oversized PTFE insulation and a unique internal geometry designed to handle significantly higher peak voltages and power levels without arcing.
This connector utilizes a professional clamp termination system. The clamp design is ideal for field service, as it provides a robust, 360-degree mechanical grip on the cable braid without the need for specialized crimping tools. This ensures exceptional pull-off resistance and high shielding effectiveness. Manufactured with a nickel or silver-plated brass body and premium, oversized PTFE (Teflon) insulation, it delivers exceptional electrical stability and long-term reliability in demanding industrial environments.
Key Technical Advantages
-
Enhanced High-Voltage Isolation: Designed with extended dielectric surfaces to prevent arcing and electrical breakdown, making it safer for high-peak power or high-voltage pulse transmission than standard interfaces.
-
Field-Serviceable Clamp Design: Enables high-reliability assembly in the field and allows for easy inspection or re-termination without industrial crimping equipment.
-
RG59 Precision Calibration: Specifically engineered to accommodate the dimensions of RG59 cable, ensuring a secure mechanical bond and stable electrical performance.
-
Rugged Threaded Coupling: The heavy-duty threaded interface provides maximum mechanical stability and vibration resistance, ensuring the connection remains secure in high-stress environments.
-
Superior Environmental Protection: The internal gasket system and compression-nut clamp provide an excellent moisture seal, protecting the cable dielectric from oxidation and moisture ingress.
