No-Conduit-Required Control Cable

Unshielded

Double Shielded

Made to TC-ER (Tray Cable, Exposed Run) standards, this crush- and impact-resistant cable eliminates the cost and hassle of installing conduit. It’s ideal for exposed runs, such as from a cable tray down to a control panel or motor control box. Support it every six feet to prevent sagging. You can flex and bend this cable during installation and adjustments, but it isn't made for continuous motion.

Unshielded—Choose unshielded wires when electromagnetic interference (EMI) isn't a concern. Equipment such as motors and pumps may have voltage fluctuations and current spikes that distort signals.

Double Shielded—With two layers of shielding, this cable offers better protection against electromagnetic interference (EMI) than single-shielded cable. It’s often used near transformers, generators, and heavy-duty motors that may have voltage fluctuations and current spikes that distort signals.
