Linear Actuators are great for moving heavy loads short distances. They differ from servo motors in that they...
(1) are linear instead of rotary
(2) are non-backdriveable, and
(3) don't require current to hold their position under load.
Despite a mini body, this linear actuator comes with a thrust of up to 128N and a stroke of 30mm when powered by a voltage of 6V.
With simple wiring, this small but practical 6V electric push rod of short-stroke can be used for applications like access control, DIY lifting projects, electric telescopic poles, etc.
