TNC
TNC Connectors
Description
Developed in the late 1950’s, the TNC stands for Threaded Neill Concelman and is named
after Amphenol engineer Carl Concelman. Designed as a threaded version of the BNC,
the TNC series features screw threads for mating. TNC connectors are miniature, thread-
ed weatherproof units with a constant 50 Ω impedance, operating from DC – 11 GHz.
There are two types of TNC connectors: Standard and Reverse Polarity. Reverse polar-
ity is a keying system accomplished with a reverse interface, and ensures that reverse
polarity interface connectors do not mate with standard interface connectors. Amphenol
accomplishes this by inserting female contacts into plugs and male contacts into jacks.
Other manufacturers may use reverse threading to accomplish reverse polarity keying.
Amphenol’s commercial grade connector offering carries the part number designation
“RFX” for easy recognition. These low-cost connectors typically utilize die cast and mold-
ed components. While performance will not be equal to the industrial or military grade
products, these connectors are ideal for use on a variety of commercial applications.
