The MMTC 5-25-3 Coil Cord is a five-conductor coiled cable from MMTC, Inc. designed to carry low-voltage control signals between moving equipment and a fixed controller. Commonly used on commercial and industrial overhead doors, rolling steel doors, and automated gates, it provides a flexible, retractable link for sensing edges, photo eyes, and pendant control stations where a traveling connection is required. It serves as a universal replacement part or upgrade for operators and accessories that specify a 5-wire coiled connection.
This 5-25-3 coil cord extends up to 25 ft and retracts to about 3 ft to maintain a tidy, snag-resistant service loop through the full travel of the door or gate. Built for repeated flexing in high-cycle applications, it is compatible with most door and gate operator brands that accept a 5-conductor control cord. Installation is straightforward: route the cord to avoid pinch points, connect the five leads per the operator’s wiring diagram, secure strain relief at both ends, and test safety circuits after restoring power. No programming is required; verify that the conductor count and extended reach meet your equipment specifications and that connected devices operate within the control-voltage requirements of the system.
