Belden a world leader in the development of signal transmission products for the broadcast, enterprise, industrial, building management, and security markets, is pleased to introduce a new line of 50-ohm N Connectors. The new series has been specifically designed and engineered to match the performance of Belden’s RF Coaxial Cables, which feature ultra-low-loss dielectrics (up to 86 percent velocity) for best attenuation in their respective size categories. These 50-ohm cables are tested and verified from 30 MHz to 6 GHz, with a maximum VSWR of 1.25:1. The cable/N connector combination also meets a maximum VSWR of 1.25:1 (equivalent to a return loss of -19 dB).

Developed specifically to meet the requirements of today’s high-speed, low loss applications, the RF Coax Cables and N Connectors can be used in a wide range of RF applications − including cellsite transmissions, broadcast STLs and RPUs, wireless microphone diversity antennas, two-way radio or life/safety system connectivity, and other RF transmission requirements.

The largest cable/connector combination (RF600 Series and NM600/NF600 Connectors) can carry over 5kW at 30 MHz and more than 300W at 6 GHz, making them ideal for low-power television, back-up transmitters, FM and TV translators and repeaters, microwave transmission, and similar applications.

Belden’s 50-ohm N Connector line is comprised of eight (8) Male N Connectors (Plugs) and eight (8) Female N Connectors (Jacks). All eight cable sizes − from the miniature RF100A (Part No. 7805) through the massive RF600 (Part No. 7977) have corresponding male and female connectors in stock, which can be ordered using the same basic part number as the cable: for the RF100 cable line, the male N connector is part number NM100; the female N connector is NF100. A Crimp Tool is also available (Part No. RFCT) that provides a full crimp each and every time.

The 50-ohm N Connectors’ insulators are made of Teflon®, the center contacts are gold-plated, and the outer contacts are either silver or nickel-plated. All other connector parts are nickel-plated bronze with a tarnish-resistant finish.

Most of the RF Cables come in three versions: outdoor (with an A suffix to the part number); riser-rated /indoor (with an R suffix); and direct burial/water protected (with a WB suffix).
