Product Operation Demonstration Video: Pair Remote to Remote Switch Package Include: 1 x Heavy Duty Linear Actuator B 1 x Receiver: S1PF-DC12 / S1PF-DC24 1 x Transmitter: CP-3 2 x Fixing Brackets B 1 x User manual The information for electric linear actuator: The stroke range of linear actuators is 0.4 ~ 80 inches or 10 ~ 2000 mm. We can also customize any stroke length from 10mm to 2000mm, such as 770mm, 1250mm, 1850mm and so on. If you want to view detailed information of linear actuators with different strokes, such as detailed drawings and dimensional drawings, please click the following link to view: Linear Actuator B Application: Mainly used for doors, windows, cellars, trapdoors, hatchways, solar tracking system, medical devices, agricultural machinery, vehicles, ships, elevator platforms, lifting tables, TV lifts, robots, cabinetries, massage sofas, electric beds, medical chairs, and other electrical equipment. It can open, close, push, pull, lift, and descend these devices. It can replace hydraulic and pneumatic products to save power consumption. Feature: High-quality products and high-quality services High strength wear-resistant gear Aluminum alloy telescopic tube and outer tube, good corrosion resistant Heavy duty design, high-power DC motor Strong thrust, up to 6000N / 600 Kgs / 1300 lbs Multiple speed options, from 3.5 mm/second to 38 mm/second Multiple stroke options, from 10 mm to 2000 mm We can customize any stroke length from 10mm to 2000mm, such as 770mm, 1250mm, 1850mm and so on. Advanced waterproof and dustproof technology Low power consumption and low noise Built-in two limit switches, linear actuator will automatically stop when stroke rod reaches the limit position. With auto-locking capability to hold load position after stopping, and no power supply is required. Maintenance-free Specifications: Optional working voltage: DC 12V or DC 24V. Unless you only have 12V power supply available, we recommend you choose the linear actuator with 24V w
