TRIAXIAL CONNECTORS
FOR BROADCASTING
BBC STANDARD
4M SERIES
4M Series (50
Ω
/ 75
Ω)
for video applications
The 4M Series have been especially
designed for triaxial video cameras in harsh
environments.
These connector models are triaxial and
available with either 50
Ω
or 75
Ω
contact.
The connector outershell has a mechanical
keying to avoid both connector/contact
rotation and signal interruption.
Being equiped with a rugged housing,
the 4M series have a high index protection
of IP66. The 4M.650 (50
Ω
version) has
been adopted by the BBC as its standard
for studio and outside broadcast cameras.
