PUR CY screened grey polyurethane control flex

PUR CY screened grey control flexible cable has a tough polyurethane outer sheath. Designed for connecting, measuring, checking and control applications in the machine, plant and tool making industries. The tinned copper wire braid screen provides protection against electrical interference.  The PUR sheath provides increased mechanical and chemical resistance when compared to standard PVC. Unbedded versions (without an inner sheath beneath the braid) have reduced overall diameters compared to bedded.

These durable yet flexible PUR CY screened cables are suitable for installation indoors or outdoors, in dry, moist or wet areas including where exposed to harsh mechanical strain or dragged over sharp/rough surfaces. These cables are resistant to mineral oils, coolant emulsions and UV-radiation.
