The Gemini Slider 500 is Gemini's 12V sliding gate motor for home gates up to 500kg, rated for 150 openings a day at up to 26 m/min. Gemini builds it in Pretoria. The motor runs off its battery while the mains supply keeps the battery charged, so the gate keeps working through load shedding. Every kit comes with the motor, a 12V 8Ah battery, two Gemini 3-button remotes, gearbox oil and the base plate.
Which kit do you need?
- Basic kit: Slider 500 motor, 12V 8Ah battery, 2 Gemini 3-button remotes, 50ml gearbox oil and the base plate. A good fit if your gate already has a rack in good condition.
- Kit with anti-theft bracket: everything in the basic kit, plus the Gemini anti-theft bracket. It is 5mm electroplated steel, makes the motor harder to take by force and guards the red release lever.
- Full kit with anti-theft bracket and steel rack: everything in the bracket kit, plus 4m of Gemini steel rack (2 x 2m). Everything for a gate that has no rack yet.
Gate longer than 4m? Add extra lengths of Gemini 2m steel rack, or use nylon rack if you would rather screw it on than weld.
Battery backup and power cuts
The Slider 500 is a battery-driven motor: the 12V 8Ah battery drives the gate and the mains supply keeps it topped up. When the power goes off, the gate carries on running for as long as the battery has charge. How many openings that gives you depends on the gate's weight, how freely it runs and how often it is used, so Gemini does not publish a number. If backup matters most, the Gemini Slider 500+ (12V 12Ah) has the bigger battery and is rated for 200 openings a day. When the battery needs replacing, a 12V 7Ah or 7.2Ah battery such as the Gemini 12V 7.2Ah battery also fits.
Going solar
The power supply in the Slider 500 is solar compatible. With Gemini's 12V solar adaptor board and a panel, the battery charges from mains, solar or both. Want it all in one box? The Gemini Slider 500 solar gate motor kit comes with a 30W panel and the adaptor board.
Make it smart
Plug a Gemlink Smart device into the comm port and open the gate from your phone over Bluetooth or Wi-Fi. The free Gemlink app shows the gate's live status and access logs, and lets you share access with up to 30 users. Prefer a motor that comes smart out of the box? See the Gemini 24V smart gate motor (Slider 800).
Safety and everyday features
Obstruction sensing is electronically adjustable and works in both directions, and there is an input for infrared safety beams. You also get auto-close (2 to 60 seconds), a pedestrian opening, townhouse mode, a courtesy light connection and an onboard receiver that holds 30 remotes, so you can add extra Gemini remotes at any time.
Gemini's installation manual and spec sheet are linked on this page, and you can compare the whole range on our Gemini gate motors page. Alectra Solutions supplies the equipment only, so have the motor fitted by your own gate installer.
Key features
- Battery backup for load shedding. The 12V battery drives the motor and the mains supply keeps it charged, so the gate works in a power cut.
- Home gates up to 500kg. Gemini's rating, for a gate on 80mm roller-bearing wheels running on a straight, level track.
- 150 openings a day. Gemini's residential rating. For a busier gate, look at the Slider 500+.
- Oil-filled worm drive gearbox. 23:1 ratio, with 30 kgf starting pull and 17 kgf rated pull.
- Obstruction sensing both ways. Electronically adjustable, plus an input for infrared safety beams.
- Auto-close and pedestrian opening. Auto-close from 2 to 60 seconds, pedestrian mode, townhouse mode and direction change.
