DC HOUSE Mini Electric Linear Actuator Stroke 4"–Force 4.5 lbs–12V | High-Speed 1.97"/sec–Weight 0.25KG Ideal for Intelligent Range Hood, Fan Blades, Cabinets, Robotics, Home Automation

Works as expected.

The media could not be loaded. I'm building an electric brake for my E-Bike and this item will push a generator/motor up against the back wheel. The switch I bought is reverse polarity so I can release the brake as well. 20nm is the minimum to apply to my back wheel but I'm hoping it will be strong enough to generate some power to my battery via ultra-capacitors and also apply some braking for the wheel. Since I'm using power it may be a trade off vs using a manual lever like a regular bike brake caliper.On my second purchase I was disappointed that the mounting hardware came lose in the box. Otherwise I am still very happy with the product.

I used this actuator as a replacement for a choke solenoid on an outboard motor remote upgrade, saved me quite a bit of money and simplified my wiring. The built-in travel limits eliminated the need for me to install & wire my own and the travel & force was perfect for my application. The factory solenoid actuator this replaced would have cost 8X as much and might not have installed as intended... the factory couldn't guarantee the fit on my engine model. I teamed this up with a mini DPDT relay that could be hidden inside the engine housing and 3D printed the parts required for the installation. Works great with my remote throttle quadrant, the choke now operates as it's supposed to and I couldn't be happier. Nice unit.

I didn’t use this actuator for its intended purpose really. I was making a disconnect for a circuit but the body and the shaft aren’t isolated. I hit it with 13kv and it instantly decided to leave the party. I have since added a block to the end of the shaft to for isolation and it works great!

Good price and fast shipping. I built an RC bull dozer and needed two of these to operate the bladeup and down. They work great. Happy with purchase.

I have purchased these Linear actuators 9 different times over the last couple of years. They have worked great but my last order I received the actuator but this time I received it with no connector on the end of the power wire. All other orders, they had a connector.

Excellent size and rating.

This was a little surprise as to how small it is and its output in power. I needed a solution for tilting a 10lbs object in a prop I was building. It was able to do so with speed. It moves quite fast and has built in limit switches so it will cut power to the motor once it has reached its range of motion. It will hold its position when stopped although It will move if overcome with enough weight I am guessing 15-20lbs. Its not silent but not terribly loud for the amount of work its doing in a short amount of time. Overall I am very happy and look forward to using more in other projects.
