COAXIAL & TRIAXIAL CONNECTORS
FOR BROADCASTING
3T SERIES
3T Series (75 Ω) for TV camera applications
Particularly intended for outdoor use, the
product range of coaxial and triaxial
connector of the 3T Series guarantees a
protection index of IP66 as per IEC 60529
standard (mated connectors).
The 3T Series models are fully intermatable
with the ULC Series size III C75 (coaxial
75 Ω) and size III TCX75 (triaxial 75 Ω).
