Flex JB / OB Control Cable

Flex JB OB Control Cable

Used as a connecting cable, measuring, checking and control cable in machine tool manufacturing, plant engineering and on assembly / production lines to meet stringent safety requirements. Suitable for fixed installation or flexible applications with unrestricted mobility without forced movement control and without exposure to tensile load. Installation in dry and moist rooms, outdoor installation not permitted.
