158EIA-HCA158-C03KT
1-5/8" EIA Connector Kit for 1-5/8" Coaxial Air Dielectric Cable, O-Ring Sealing

Rev : P2 | Rev date : 14 Feb 2025

RFS Technologies’ high-performance air dielectric coaxial cable connectors are designed to ensure a top-quality connector-cable interface, while simplifying and accelerating installation. These connectors, rigorously tested for mechanical and electrical compliance, can be installed quickly and securely with basic hand tools.

The outer contact features a tab flare and integrated O-ring sealing, enhancing both ease of use and durability. Designed for flexibility, the connectors are configured as gas-stop types but can be converted to gas-pass simply by drilling through the insulation.

With a flange interface that meets international EIA and IEC standards, these connectors are built for seamless compatibility. Each C03 series connector is packaged with a flange gasket, coupling element, and necessary hardware—everything required for a reliable and efficient connection.

FEATURES / BENEFITS

High power rating for enhanced performance: Built to handle high power levels, these connectors ensure reliable performance and efficient signal transmission, even under demanding conditions.
Quick, labor-saving installation: Installers can attach these connectors easily with basic hand tools, reducing time and effort on site.
Adaptable to a variety of applications: Designed as a gas-stop type, each connector can also be converted to gas-pass by drilling, offering flexibility to match specific needs.
Broad compatibility across systems: The flange interface complies with EIA and IEC standards, allowing for seamless integration into different setups.
Connector kit convenience: Each C03 series air cable connector comes with a flange gasket, coupling element, and complete hardware kit for mating with another flange, eliminating the need for additional parts and simplifying ordering and stocking.
