Custom Linear Actuators

Custom linear actuators

Do you need a custom linear actuator for your next product or project? Actuonix Motion Devices can help. We pride ourselves on manufacturing the largest selection of affordable micro actuators available. Even still, we regularly get requests from customers who require a custom actuation solution that is outside of our regular range of products.

Custom Linear Actuators That Meet YOUR Specifications

At Actuonix, we manufacture all of our products. Unlike some of our competitors, our team of engineers designs every piece of our actuators from our headquarters in Western Canada. Because we control the entire production process, we can alter our designs to suit your needs.

Do Custom Electric Actuators Require A Minimum Order Quantity?

Yes, we require a minimum MOQ of 500 for basic actuator modifications. The MOQ may be more or less depending on what your particular needs are. Below are some examples of customizations that we can produce with a minimum order quantity of 500 units.

Change Electrical Connector

There are lots of different types of connectors out there. If you're installing many actuators in your project, it might be worth having us customize a cable for you. Installing a custom linear actuator cable to match what's already available on your device will save you time and money.

Longer Or Shorter Connection Wire

Not only can we change the cable, we can also customize the length of the cable. Whether you want your cables to be 2 inches or 20 inches, we can work with you to produce a custom cable that will work for your application.

Modifying Limit Switch Position

Our internal limit switches are non-adjustable. There are other ways to limit the stroke of your actuator that might work for you. If you're ordering a large quantity of linear actuators and you want to limit the stroke without the use of external switches or an LAC board, talk to our sales team about modifying a stock product to your specifications. We will have the switches repositioned at our factory.

Shortening Actuator Stroke 

If simply limiting actuator travel wouldn't work for you, and you need a device with a physically shorter stroke than what we offer, we can do that as well. We do this type of actuator customization for our existing customers already and know the process inside and out.

Custom Rod End Attachments

All of our micro linear actuators (with the exception of our NXT and T16 lines) come with the stock clevis end tip. You will also find a threaded end tip inside the included hardware kit. Most of our clients are able to make one of these tips work for them. If however, you require a different means of attachment, we can work with you to design an end tip that will integrate seamlessly into your design.

Fitting A Motor/Gearbox With A Custom Gear Ratio

Though our line of electric actuators comes with a variety of gearing options, there are others available. We can work with our motor supplier to provide actuators with a custom gear ratio to better suit your force and speed requirements.

Changing Lubricants To Facilitate Low-Temp Operation

If you are planning on operating our miniature actuators in an extreme environment, you may need to order devices with a custom gear oil to facilitate low-temperature operations. The stock gear oil works well in a wide range of temperatures but can become too thick when subjected to extremely low temperatures.

In addition to the linear actuator customizations mentioned above, we can make more significant design alterations up to and including designing an entirely new product. The minimum order quantity for major customization begins at 2000 units.

If you're looking for an affordable custom actuator for your next product design, you're in the right place. Nobody can match Actuonix's selection of actuators. And if none of our 164 stock models works for you, we can make something that will, and we can do it within your budget.

We want to you get the right micro linear actuator for your needs, at the an affordable price. That's why we included a complete mounting hardware kit with every actuator we sell. Other companies charge $8-10 for just the hardware kit.

How To Use Relays To Control Linear Actuators

linear actuator with relay

In this post I'm going to go over how to use a relay to control the motion of a linear actuator. I'll cover not only how to use a relay to control your actuator, but also some situations where you might want to. We offer a simple relay kit in our store that is designed to work with electric micro linear actuators.

For larger projects, there are relay boards available with 2, 4 and even 8 channels. You can find larger relays at RobotShop.

What Is A Relay

A relay is simply a switching mechanism. It allows you to control a big switch with a smaller switch without the current of the primary load running through the smaller switch. 

This is important in applications where only a small amount of current is available to control a switch as well as applications where the switch you want to use is not rated for the current your load requires.

How A Relay Works

As I mentioned above, a relay adds a second switch into your system. Basically, a relay is just a switch that is controlled by a smaller switch.

They work by using a small current form the input source to activate an electromagnet. The electromagnet pulls a switch and allows a higher current to flow through the opposite side of the relay. It's a cheap and effective way to switch a larger load.

Why Use A Relay

Sometimes you want or need to use a switch that is not rated for the load of the device you're working with. This requires a relay to switch the higher load. 

Another example is if you're using a microcomputer or microcontroller such as a Raspberry Pi or an Arduino. They are only capable of a very small electrical output. A relay would be required to handle any significant electrical load.

If you're interested in driving a single actuator via Arduino. Our -R series linear servos might be a better option for you. Many Arduino boards are capable of driving one actuator directly off the board and since they're a plug and play replacement for standard rotary servos, they're easy to use.

 Some Examples of When You Might Want To Use A Relay

Vehicle Applications

Relays are popular for vehicle automation applications. They are ideal because it's possible to tap into an existing circuit within the vehicle to use as a switch for the relay. An example would be if you're using actuators to drive pop-up headlights, a relay could activate them when you turn on your headlights or even your ignition.

The low-power side of a relay draws very little current so it's often possible to tap into an existing circuit without drawing too much current for the circuit to handle.

Low-Current Applications

This could be any microcontroller application. We have thousands of customers using our actuators with Arduino. Adding in a relay kit makes switching power on and off safe and fairly simple. 

Momentary Applications

By using our DPDT relay, you can make your actuator extend with the push of a button, and retract automatically when you release the button. By reversing the actuator's two leads, it's possible to reverse this effect. This would cause the actuator to remain extended full-time, and retract at the push of a button.

How To Connect The Actuonix Relay Kit

I've included a wiring diagram below that shows you exactly how to connect your actuator to the Actuonix relay kit. These wiring instructions remain the same whether you're using a latching or momentary switch.

We filmed a video recently to demonstrate how you can use our DPDT relay kit to actuate your device momentarily and have it retract automatically.

Our actuator relay kit is just one of the many linear actuator accessories we carry. In our store you'll find a full line of actuator controllers, switches and accessories to make sure that you can control your device the way that you want to.
