The Hörmann SilentDrive SD7500 Head Only Garage Door Opener is a replacement operator head for existing Hörmann SilentDrive systems, designed to deliver smooth, quiet door operation with soft start/stop control. Intended for residential sectional garage doors, this operator head integrates a 315 MHz rolling code radio receiver for secure remote access and connects to standard North American power (120V AC, 60 Hz). Head Only indicates the motor unit is supplied without the rail, trolley, belt, door arm, mounting brackets, or external safety sensors; it is meant to be paired with compatible Hörmann SilentDrive belt-rail assemblies and accessories already installed or sourced separately.
Engineered for reliability and safety, the SD7500 supports electronic travel limit setup, force monitoring, and automatic reversal when an obstruction is detected, and it complies with UL 325 requirements when used with approved photo-eye sensors. It is compatible with Hörmann 315 MHz rolling code transmitters and receivers used in the U.S. market (such as HSE/HSM series at 315 MHz), making it a practical replacement part for existing Hörmann systems rather than a universal opener head. Installation typically involves mating the operator head to the correct Hörmann rail for the door height, wiring and aligning the safety sensors, and programming remotes and limits via the learn/setup controls on the unit. For safe and optimal performance, use on properly balanced doors and have installation and setup performed by a qualified technician.
