Stroke length: 1 inch / 30 mm; Travel speed without load: 9.5 mm/s; Load capacity: 90 N / 20.3 lb; Input voltage: 12 VDC. The linear actuator is constructed from high-quality aluminum alloy, providing strength, durability, and resistance to rust for long-term use. This mini linear actuator features a compact and lightweight design. It includes short-circuit protection, overload protection, and over-voltage protection, making it suitable for applications such as robotics. The electric linear actuator operates on 12 VDC power. When connected with correct polarity, the actuator extends; reversing the polarity causes it to retract. Mounting brackets are included for easy installation. Mini linear actuators are commonly used in agricultural machinery, engineering equipment, factory and home automation systems, robotics, cabinets, and industrial electric lifting systems.
