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

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.

So small! Works great when space is tight. A bit on the noisy side. Especially if you're using a battery to lift something. Power supply helped reduce this issue a bit.

A little challenging for a non-tech to figure out when connected to the controller, but working great as a method of lifting a lid to air some cuttings a couple of times a day.

This Actuators are small and strong very fast..very slim too good for small projects.

Worked great until it stopped after a while. I’ve gone through two of these within a year. Easy install and the speed worked for my project.

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.

This broke after about 10 minutes of use. Not impressed was working well withing the specs.

These are very hard to come by. I ordered one previously and it was 5 stars! I ordered another one and I was sent the 30mm one instead of the 10mm one I ordered. Check the contents of the box as soon as it arrives. These are great actuators!
