YY JB/OB grey control cable is designed for connecting, measuring, checking and control applications.
These flexible and versatile YY JB/OB cables with colour coded cores work well in environments with only light mechanical stress.
Suitable for installation in dry and moist rooms, outdoor installation not recommended.
If protection against electrical interference is required please see our range of CY screened control cables, If protection against mechanical damage is required please see our range of SY armoured control cables.
