HN M CLAMP for LMR400/RG8/RG11/RG213/RG393 Cable

Description

The HN (High-Voltage N) series is a specialized RF interface designed for applications where standard N-type connectors would fail due to voltage breakdown. This male (plug) variant is optimized for the 10mm (0.400″) diameter cable class, including low-loss LMR400, industrial RG8/RG213, the high-capacitance RG11, and the high-temperature RG393. The HN interface maintains the ruggedness of the N-series but features extended PTFE insulation and a unique internal geometry to handle significantly higher peak voltages and power levels without arcing.

Maintaining a precise 50-Ohm impedance, this connector utilizes a professional clamp termination system. The clamp design is ideal for high-power applications as it provides a robust, 360-degree mechanical grip on the cable braid, ensuring exceptional pull-off resistance and high shielding effectiveness. Furthermore, the clamp mechanism allows for reliable field installation without the need for specialized crimp tools. Manufactured with a nickel or silver-plated brass body and premium, oversized PTFE (Teflon) insulation, it delivers exceptional electrical stability across the VHF and UHF spectrums.

Key Technical Advantages

• Superior High-Voltage Handling: Designed with extended dielectric surfaces to prevent arcing and electrical breakdown at high peak power levels, outperforming standard N-type interfaces.

• Field-Serviceable Clamp Design: Enables high-reliability assembly in the field and allows for disassembly and inspection without the need for specialized industrial crimping equipment.
