Uninterrupted Security and Dependable Power
The Gemini 12V 12Ah Sliding Gate Motor Kit serves as a self-contained residential security asset built for heavy-use domestic gates weighing up to 500kg. By utilizing a high-capacity 12V 12Ah sealed lead-acid battery, this motor offers substantially longer backup life and more continuous opening cycles during power outages compared to standard entry-level 7Ah gate motors. The motor drives the gate smoothly using a rugged rack-and-pinion mechanism powered by a robust, oil-filled reduction gearbox for whisper-quiet performance and long-term durability.
Smart-Ready and Feature-Rich Integration
Encased in an iconic, weather-resistant yellow cover, this motor is built to withstand harsh outdoor conditions. It comes equipped with convenient operating features including soft start/stop technology to reduce mechanical stress, electronic obstruction sensing for immediate safety stop-reversal, and adjustable automatic closing parameters. It is also smart-ready, allowing you to add remote monitoring modules or connect solar integration components as your property requirements evolve.
Rack is bought separately here, because the length depends on the gate. A gate of about 4 metres needs 4m of it. If your gate is bare, one of the kits below works out cheaper than adding rack on its own.
Key features
- Extended 12Ah Load-Shedding Backup Equipped with a high-capacity 12Ah sealed lead-acid battery, this kit provides a superior power reserve that keeps your gate cycling multiple times through prolonged blackouts, far outperforming conventional 7Ah setups.
- Quiet Oil-Filled Worm-Drive Gearbox Features a high-torque 120W motor linked to a 33:1 ratio oil-filled worm-drive gearbox. This internal design ensures ultra-quiet operation, reduces friction, and extends the mechanical lifespan of the unit.
- Comprehensive Electronic Safety Built with intelligent protection profiles including adjustable electronic obstruction sensing (both opening and closing directions), soft start/stop speed ramp curves, and an easy-access manual key override system for absolute peace of mind.
- Weatherproof and Robust Shell The self-contained automation assembly is shielded by a highly durable, weather-resistant protective cover designed to safeguard internal electronics and mechanical gears from severe outdoor conditions.

Questions people ask
No, this specific kit configuration does not include the nylon or steel gear rack. It is perfect if you are upgrading an older gate system where the existing rack is already installed and in good condition.
The 12Ah high-capacity battery yields significantly more standby time and consecutive gate openings during power failures compared to traditional 7Ah entry-level motors. The exact duration depends on your gate's physical length, weight, and operational frequency.
Yes. The motor is fully compatible with solar setups. To switch to solar charging, you will simply need to add an official Solar Adaptor Board along with a solar panel array.
Yes, the motor includes built-in electronic obstruction sensing that stops and reverses the gate immediately upon encountering an object. For ultimate safety, it is highly recommended to wire optional infrared safety beams across the driveway.
