Product details

TNC Plug, Right-Angle Crimp, 11 GHz

The 031-2381-1: It carries the threaded coupling that distinguishes TNC from BNC — the thread prevents vibration from backing the nut off, so the connection stays tight in an enclosure or on a panel where the cable gets bumped.

If you are building a harness for a 50 Ohm system on any of those cable types, this is the plug that matches the line.

Durability and Field Life

Rated for 500 mating cycles — that is the threaded coupling wearing the plating, not the contact beam fatiguing. The nickel body finish resists corrosion in a humid cabinet or outdoor enclosure. Single-port design, so one cable per connector — no daisy-chaining through the body.
