Product Questions

What are the included accessories for?

L12, L16 and P16 accessories:

We have included new mounting
brackets and spacers for holding the square aluminum shaft housing secure and level with the actuator’s body. The spacers are specific for each model and are clearly marked.

Can I slow my actuator down?

Yes, by lowering the voltage you drive it with. The voltage specified for each actuator on the data sheet is the maximum allowed. If you use a lower voltage the actuator will move more slowly, and push less force. To lower the voltage you can use fewer batteries, add a voltage regulator to your circuit or use PWM of the drive voltage. There is a minimum voltage required to overcome the friction inside the actuator, and this will depend on the load you attach to it. Please note: the minimum voltage for the L12-I & R types and the LAC is 3.5 volts for the control circuit to operate.

NOTE: if using a “P” series actuator with our LAC board, you can adjust the speed of the actuator through the speed adjustment pot located just above the X4 connector block. You will have to power cycle the LAC to load the new settings.

You can find the datasheet for our LAC board

How can I check which products are in stock?

You can check our stock status two ways:

1. From our home page click on the "Company Information" tab, scroll down to the "Inventory" tab and you will see another drop-down of all our products. Click on the one you're interested in to view our stock.

2. From a product page, you can click the inventory tab, within it there is a link to view the inventory of that product.

Will 2 actuators of the same voltage and gearing run at the same speed?

The speed of 2 actuators of the same voltage and gearing can vary due to internal friction variances. However if you need to have 2 actuators running at the exact same speed, send us an email. Quite often we can test a pair for you to be as close to the same speed as possible.

Do you have 3D models of your actuators available for download?

Yes, you can find all of our downloadable files on our Product Documentation page.

How do Actuonix Micro Actuators work?

All Actuonix micro linear actuators use a lead screw driven by a PMDC motor to create linear motion from a DC voltage. When power is removed they will hold their position. If a force large enough to overcome the internal friction is applied, the actuator will back drive.

How long will my actuator last?

The life will vary greatly depending on your application. Everything from load, temperature, humidity, speed, duty cycle and voltage stability will affect the lifespan. We encourage our clients to do their own testing to determine our product's lifetime suitability for their particular application. To get the longest possible life from your actuator see these tips.

How to light an LED with a PQ12 “S” series actuator when the limits are reached

Here is the link to a circuit diagram showing how to connect a PQ12 “S” series actuator to a light an LED when the limit switch is engaged

Can I paint my actuator?

Sure you can! We have had great success with Plasti-Dip spray. Be careful not to paint the actuator shaft, just the exterior housing. NOTE: Actuators can not be returned after painting.

I can't get my LAC board to work

Sometimes, the LAC boards aren't loaded correctly with their default values. Before contacting tech support, please try the following 3 things:

Double check your connections, and that you have power to the + and – terminals of connector block
2. Check that all four of the blue potentiometers on the LAC are turned fully clockwise.
3. Power the LAC off and then back on to load the default settings.

Now try the LAC again. We have a video series on using our LAC board on your YouTube channel, you may want to check that out as well.

If you are having trouble installing the LAC software's drivers, our support department has a fix for that. Some builds of Windows 10 will not install the LAC drivers properly.

Can I power my LAC board from USB?

No you can not. USB alone cannot provide enough power for the LAC board and an actuator. You will need to provide DC power to the positive and negative terminals of X6 via a battery pack or external DC adapter. This voltage must be the same as the actuator's required voltage . (6VDC or 12VDC).

The light on my LAC board won't come on

The light will only come on if the board has both power and a valid input signal. If the LED won't come on be sure to check the data sheet to ensure that you have a valid input signal connected properly.

Where can I download product documentation?

All of our product documentation and data sheets can be found here: Product Documentation .

I have the datasheet but what does it all mean?

Check out this Tech Note for an explanation of the terms and units on the datasheet.

I need help with Arduino

We do not offer Arduino support. We have however put together some information and links to articles about using our products with Arduino. You can find that page here.

Will the “R” series linear servos replace the servos in my RC plane/car/boat/robot?

The L12-R, L16-R or PQ12-R are designed to be a plug-and-play replacement for RC rotary servos and will work with most RC receivers.
