The TRAYCONTROL 550 TPE is a flexible, oil-resistant control cable with blue- or red-colored conductors approved for open, unprotected installation in cable trays from power sources/control units to the machine. The TRAYCONTROL 550 TPE was developed to help offset the need for PUR cables in tray applications. The specially blended TPE has been designed to perform as well as standard PUR cables with the added benefit of being able to transition from cable trays to free air, an installation method not permitted for PUR cables. The special combination of TC-ER, PLTC-ER and ITC-ER allows this cable to be used as a connecting cable for AC, DC or control wiring in accordance with NFPA 79 Edition 2007. Its oil resistance (Oil Res I & II) guarantees a long service life for machine tools in industrial applications located in dry, damp and wet environments such as the automotive, food and beverage industries, or other various production lines found in harsh locations.
