The 31-220H is a coaxial connector system widely used in the wireless communication and broadcasting industry for reliable transmission of signals. This type of connector comes in two versions: a UHF version with a 5/8-inch thread and an N Type version with a 3/4-inch thread. Both versions provide connection qualities that are equivalent to the highest standard in the industry.

This connector was designed for the transmission of radio frequency (RF) and microwave signals at frequency ranges of 10MHz-3GHz. It has a snap-on mating construction and a series of robust features contributed to the ruggedness of the 31-220H. This has made this series of connector especially popular for applications in broadcasting, remote telemetry, industry automation, etc.

The 31-220H is designed with self-locking, mechanical coupling. It features a threaded coupling mechanism and quick screw nut installation. The threaded body keeps the connection reliable and prevents any signal loss caused by vibration. Additionally, the connector is designed to provide excellent humidity and temperature resistance, thus making it suitable for use even in harsh outdoor environments.

The working principle of the 31-220H is based on the principles of electromagnetic shielding and impedance matching. The connector is mainly composed of a central contact pin, a shield, and an outer threaded ring. The interference of unwanted signals is reduced by providing a wave-resistant shield around the contact pin. The outer threaded ring ensures a precise mating and a reliable connection between the device ports.

The 31-220H supports various cables, such as 0.086",0.146",0.429"and 0.501"OD cables with varying inner conductors. It supports impedance range of 50Ω and 75Ω. Moreover, the 31-220H is available in several different mounting configurations, including bulkhead, panel-mounted and through-hole. The panel-mounted connectors are designed for easy and quick installation and provide flexibility for the repair and maintenance of the cable connection.

The 31-220H is a robust, reliable and widely used coaxial connector that is suitable for various radio frequency and microwave applications. It offers excellent connection qualities and provides excellent protection against hum and RF interference, making it ideal for extreme environment applications.
