The LiftMaster 50105 is an OEM coiled cord assembly with four 18 AWG conductors and an approximate 20 ft reach, designed for moving-door and gate applications. It provides a flexible, retractable connection between the operator/control box and devices mounted on a moving panel, such as monitored or non-monitored safety sensing edges on sectional and rolling doors, sliding gates, and swing gates. As a replacement part for LiftMaster commercial door and gate operators, it carries low-voltage control signals while the coiled design helps prevent cable snagging and reduces strain during repeated door or gate cycles.
With 4-conductor wiring, the 50105 supports edge circuits that require multiple conductors (for example, monitored 10k resistive edges when supported by the operator) or the routing of two separate 2-wire accessories across a moving span. Installation is straightforward: route the coil to avoid pinch points, secure proper strain relief, and land the color-coded leads on the operator and safety device terminals as directed by the respective manuals; no programming is required for this passive cable. Use only with compatible LiftMaster commercial operators and approved safety devices, and install in accordance with UL 325 and local codes. This 4-wire 18 AWG coil cord is a practical replacement solution for maintaining reliable low-voltage connectivity in residential or commercial door and gate systems where a retractable cable is needed.
