The MMTC 2-12-2 Coil Cord is a retractile, two-conductor cable assembly designed for moving-door applications, providing a flexible connection between a sensing edge, photo eye, or other traveling device and the door or gate operator. Commonly used on overhead sectional doors, rolling steel doors, and automated gates, this coiled cord maintains reliable continuity as the door cycles, helping transmit open/close commands or safety-edge signals to the control unit. The 2-12-2 designation is widely recognized in the industry to indicate a two-conductor coil with an approximate 12-foot working coil section and about 2-foot straight leads on each end for termination, making it a straightforward replacement part for worn or damaged cords.
Engineered for low-voltage control circuits typically used with door and gate operators, the MMTC 2-12-2 Coil Cord supports normally open or normally closed safety-edge wiring depending on the system’s requirements. It is compatible with a broad range of MMTC and third-party operators and sensing edges that accept a two-wire coiled cord, making it a practical universal replacement or upgrade in both residential and commercial applications. For best results, route the cord to avoid pinch points, secure strain relief at both ends, and follow the operator and edge manufacturer wiring diagrams and safety instructions; do not use this cord for line-voltage applications. This durable retractile cord is built to withstand routine extension and retraction during daily door cycles, helping maintain dependable communication between the moving edge device and the control panel.
