Precision Micro Automation for DIY Projects and Smart Homes
The 12V Mini Linear Actuator provides precise 30mm push-pull motion, making it the perfect mechanical muscle for space-constrained DIY, STEM robotics, and smart home projects. Instead of relying on complex servo and gear setups that require constant calibration, this all-in-one linear motor translates 12V DC power directly into smooth, straight-line movement. This simplifies your mechanical designs significantly. Whether you are building a custom automated drawer, a hidden pop-up camera mechanism, or a miniature trapdoor, this actuator delivers consistent, repeatable strokes every single time. Its straightforward operation means you spend less time troubleshooting mechanical linkages and more time perfecting your project's core functionality.
High 150N Force in an Ultra-Compact Body
Despite weighing only 46.7g and measuring less than 10cm in length, this Miniature Actuator delivers an impressive 150N of force (approximately 15kg of pushing/pulling power). This exceptionally high power-to-weight ratio allows it to easily push, pull, or lift heavy flaps, miniature doors, and custom RC construction vehicle arms without stalling under load. The internal gearing is engineered to maximize torque while maintaining a compact footprint of just 9.6 x 2 x 1.5 cm. This means you can easily conceal the mechanism inside tight enclosures, wall cavities, or small 3D-printed chassis where traditional motors simply would not fit. The aluminum alloy shaft ensures durability and resists bending even when operating near its maximum load capacity.
Seamless Integration with Arduino and RC Systems
This 12V Linear Motor is universally compatible with standard motor drivers, relays, and DPDT switches, making it incredibly easy to integrate into both manual and microcontroller-based systems. For STEM students and robotics hobbyists, it pairs perfectly with an Arduino or Raspberry Pi when routed through an L298N H-Bridge motor driver. This allows you to write simple code to automate the extension and retraction based on sensor inputs, such as light or motion. For RC enthusiasts, it can be connected to a receiver-controlled relay switch to operate dump truck beds or retractable landing gear directly from your remote control. The included 27cm wiring harness provides plenty of length to reach your control board without needing immediate splicing.
Pro Tip from Our Technicians
To make the actuator retract after it extends, you must reverse the polarity of your 12V power supply, and our Sham Shui Po technical team strongly advises using a DPDT (Double Pole Double Throw) toggle switch for manual control. Simply connecting and disconnecting the power will only make it move in one direction and stop. By wiring a DPDT switch in a reversing configuration, you can easily flip the switch up to extend the rod and down to retract it. Furthermore, please be aware that this model does not have built-in limit switches. This means you must cut the power as soon as it reaches the end of its 30mm stroke to prevent the internal motor from burning out. If you are automating this, we recommend adding external micro-switches to your circuit to automatically cut the power when fully extended or retracted.

FAQ Section
FAQ Section
- How do I make the linear actuator retract after it extends?To make the linear actuator retract, you must reverse the polarity of the 12V DC power supply. Connecting the red wire to positive and black to negative will extend the rod; swapping them so black is positive and red is negative will retract it.
- Can I control this 12V linear actuator using an Arduino?Yes, you can control this linear actuator with an Arduino by using an external motor driver module. Because the actuator requires 12V and reverse polarity to operate, you must route your power through an H-Bridge motor driver (such as an L298N) which the Arduino can then control via logic signals.
- Is this mini linear actuator waterproof for outdoor use?No, this mini linear actuator is rated IP60, meaning it is protected against dust but is not waterproof. It should only be used in dry, indoor environments or housed within a waterproof enclosure if used for outdoor DIY projects.
- Does this actuator come with the necessary mounting hardware?Yes, this 12V Mini Linear Actuator includes two metal mounting brackets along with the necessary securing pins. These brackets attach to the "no ear" flat mounts on the rear and the tip of the rod, allowing for secure pivot installations.
- Can I get advice on how to wire this actuator at your store?Yes, you can bring your project details to Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po for expert wiring advice. Our technical staff can help you select the correct DPDT switches or motor drivers needed to safely control the forward and reverse motions of this actuator.
