Cabinet & Lid Linear Actuator Planning Guide
Cabinet doors, lift-up panels and hinged lids require mechanism-level planning. Door or lid weight alone is not enough to select an actuator because hinge geometry, actuator angle, leverage and friction change the required force throughout the motion.
1. Define the Motion
Document the moving mass, hinge or pivot locations, desired opening angle, opening path and any guide or linkage friction.
2. Calculate Force from the Geometry
Determine the actuator force across the required motion using the actual mounting points and leverage. Avoid selecting a model from a generic door-weight multiplier.
3. Determine Stroke and Installation Length
Calculate the required actuator travel from the closed and open geometry, then confirm the actuator fits at both positions. Mounting geometry and available cabinet space can be as important as nominal stroke.
4. Compare Speed and Duty Cycle
Use the load-speed specification when evaluating motion under working load. Confirm the expected operating frequency against the actuator duty-cycle rating.
5. Verify Voltage and Control Requirements
Select 12V or 24V according to the electrical architecture and verify current, switching, controller, feedback and synchronization requirements separately. Smart-home or remote-control compatibility should not be assumed unless the complete control system is verified.
6. Evaluate the Installation Environment
Consider temperature, dust, moisture, electrical connections and enclosure requirements. An IP rating is one selection factor and does not by itself prove suitability for a specific cabinet location.

Frequently Asked Questions
Can I choose an actuator from cabinet-door weight alone?
No. Hinge geometry, actuator angle, leverage and friction affect the required force.
How do I determine cabinet actuator stroke?
Use the closed and open mechanism geometry to calculate the required actuator travel, then verify installation length at both positions.
Does 12V or 24V determine controller compatibility?
No. Voltage must match, but current, switching method, signals and controller ratings must also be verified.
Is one actuator always enough?
No fixed actuator count applies to every cabinet mechanism. The structure, load distribution, guides and stability requirements determine the system design.
