BNC connectors allow ease of engagement and disengagement using bayonet couplings and overlapping dielectrics. Three connector installation methods are offered. The "O" crimp design allows a uniform compression on the cable braid enhancing the electrical performance. The Hex crimp design is the more traditional connecting method. The twist-on connection design requires no special tooling to install. Available for Plenum 59/62, Belden 88241, 89269, Berk-Tek BTDC-59, BTDC-62, and equivalent construction only.
