10 pair Tyco QDF E Termination Magazine blocks
The QDF (Quick-Connect Distribution Frame) family of products provides a reliable, quickand easy to use system for wire anagement.
The QDF magazine utilises unique split cylinder insulation displacement contact (IDC). This provides fast and reliable wire termination while eliminating time-consuming wire stripping and wrapping or soldering. The 2-wire capacity of the split cylinder allows teeing on to (commoning) circuits.
It is a 10-pair magazine designed for applications in which there is or will be a need for protecting, testing or breaking the circuits.
This includes distribution frames and on customer premises, as well as in outside plant installations.
