CY JB/OB clear screened control cable with colour coded cores has a bedded tinned copper wire braid screen which provides excellent protection against electrical interference.
These flexible and versatile CY JB/OB cables are used for connecting, measuring, checking and control applications.
Suitable for installation in dry and moist rooms, outdoor installation not recommended.
If protection against electrical interference is not required please see our range of YY control cables, If protection against mechanical damage is required please see our range of SY armoured control .
