Product details

75 Ohm BNC Plug-to-Plug Adapter for Video and Telecom Runs

The Amphenol RF 031-218-75RFX is a straight BNC to BNC adapter configured as plug to plug with male center contacts on both ends. Its 75 Ohm impedance targets video distribution, broadcast, and telecom infrastructure where 75 Ohm cabling is standard, rather than the 50 Ohm world of general-purpose RF test gear. The dielectric is polyoxymethylene (POM) acetal. Maximum operating frequency is 4 GHz, which covers SDI video, baseband telecom, and most CCTV signals.

Frequently asked questions

Where can I buy Amphenol 031-218-75RFX?

Submit a request for current availability and pricing; no stock-holding or lead-time figure is carried on this listing.

What is the impedance of Amphenol 031-218-75RFX?

75 Ohm.

Is 031-218-75RFX male or female?

Male to male — both adapter ends are BNC plugs with male center pins.

Can I use a 75 ohm BNC adapter with 50 ohm cable?

Using a 75 Ohm adapter in a 50 Ohm system will create an impedance mismatch, causing signal reflections and increased VSWR. For best signal integrity, match the adapter impedance to the cable and system impedance.
