Continuous-Flex Cable

Unshielded

Shielded

Often used in automated applications such as robotics and cable carriers, this cable withstands continuous motion without degrading data or signal transmission. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material. Rated for use in ISO Class 1 or ISO Class 2 clean rooms, this cable releases minimal particles into the air, helping you to maintain the cleanest possible environment.

Use unshielded cable in applications where signal interference is not a concern.

Shielded cable has a layer of braid that blocks signal interference from nearby equipment and devices.

Choose cable with PVC plastic outer insulation for general purpose indoor applications. Their protective layer resists abrasion, though it has the highest bend radius compared to other materials.

CE marked cable meets European health, safety, and environmental protection requirements.

Bend radius is the point to which the cable will bend without being damaged. It is measured from the center of the bend to the edge of the cable. The smaller the radius, the more the cable can bend.

Double Shielded: Automation, Interference Shielding
Flexible
Temperature Range: -40° to 220° F
Insulation: Modified Polyphenylene Ether (mPPE) Plastic

Nearly two-thirds the diameter of standard control cable, this cable fits in tight spaces. The modified polyphenylene ether (mPPE) insulation is less than half the weight of the PVC insulation found on standard control cable, yet is more abrasion and cut resistant. Use it to send signal and data to operate, measure, or regulate automated equipment that requires cable to periodically flex and bend. It’s often used with conveyors, CNC machines, and to connect equipment to a control panel. Cable is flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Use unshielded cable in applications where signal interference is not a concern.

Double shielded cable has a layer of braid and foil shielding that provides excellent protection against signal interference from nearby equipment and devices.
