TNC series connectors
are designed as a threaded version of the BNC, the
TNC series features screw threads for mating. TNC
are miniature, threaded weatherproof units with
constant 50 Ω impedance and they operate from 0
- 11 GHz.
There are two types of TNC connectors: Standard
and Reverse Polarity. Reverse polarity is a keying
system accomplished with a reverse interface, and
ensures that reverse polarity interface connectors
do not mate with standard interface connectors.
Cable terminations are available in crimp , clamp,
twist-on and solder configurations. The 7/16"-28
thread coupling provides positive mating.
Although their rugged design was initially developed
for shock and high vibration environments, TNC connectors
are widely accepted and used for data transmission,
medical equipment, cellular mobile telephones, test
equipment, microwave components and aerospace applications. |
