Belden Type TC cables are suitable for applications requiring sunlight, moisture, and vapor resistance. They have approval for use in wet and dry locations. These tray cables are also suitable for use in outdoor and direct burial applications and raceways when supported by a messenger wire. Unshielded Belden Type TC cables are applicable in control applications installed in metallic conduit. Overall shielded cables are suited to control applications with signal transmissions over 100 millivolts, but not in applications with excessive crosstalk.
