Understanding 12V Linear Actuators
What is a 12V Linear Actuator?
A 12V linear actuator is an electromechanical device that provides linear motion when powered by a 12V DC source, such as a battery or power supply. It is designed to push or pull loads in a straight line, making it ideal for various applications ranging from home automation to industrial machinery.
How Do 12V Linear Actuators Work?
12V linear actuators operate using an electric motor that drives a screw or a belt mechanism. When the motor rotates, it moves the actuator rod in a linear direction, either extending or retracting it. This motion can be controlled using a switch, remote control, or an automated system for precise operations.
Key Features of 12V Linear Actuators
