About Wire and 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.

Oil-Resistant Continuous-Flex Cable

This cable has an insulation with excellent resistance to oil, so it can be used near motors and equipment that require oil lubrication. Often used in automated applications such as robotics and cable carriers, it 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.

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.

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 measurement, the tighter the bend.

Use For: Automation, Continuous Motion
Continuous Flex
Temperature Range: -30° to 175° F
Insulation:
Outer: Polyurethane Rubber
Inner: TPE Rubber

With a life span of more than 20 million high-speed flex cycles, this cable lasts twice as long as standard continuous-flex cable so you have to replace cable less frequently. Often used in automated applications such as robotics and cable carriers, it withstands continuous motion without degrading data or signal transmission. The polyurethane rubber insulation resists abrasion, chemicals, and oil.

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 measurement, the tighter the bend.
