HN-Type connectors are medium sized, weatherproof units designed for high voltage applications. These connectors feature captivated contact design which prevents contact recession under extreme temperatures and mechanical stresses.

HN connectors are capable of handling up to 5,000 volts, making them ideal for use in high power industrial applications from DC to 4 GHz.
