Product and Ordering Information
In many applications the installation of multipair cables is more economical than pulling several single pair wires. The most common calibrations such as JX, KX, and TX are readily available in cable form.
All cables are furnished with twisted pairs and 100% coverage shield tape providing maximum reduction in magnetic and electronic interference.
The available standard cables are listed in the following tables. Special constructions can be quoted to your specifications.
