An Essential Guide to Choose the Right Solenoid

Choosing the right solenoid can be a daunting task, although it doesn’t have to be if you know where to look for advice and the best products.

Since solenoids come in a variety of configurations that use different parts it can be hard to figure out exactly what you’re looking for.

Additionally, making a comparison of force curves as well as specification sheets take a lot of time.

With all of this in mind, it’s a good idea to seek professional help from an expert knowledgeable in solenoid technology. However, to get you started, read through this comprehensive guide better understand what you really need.

Finding the right rotary solenoids can be based on five traits, which include function, stroke length and force, duty cycle, size, and voltage. To begin with, you need to analyze these five traits and find out which ones are pre-determined in your application’s requirements list and note them down.

Knowing more of these traits can be quite helpful in your solenoid selection process. However, you don’t have to have all of them to find what you need.

There are so many other parameters to consider, and you’ll realize that some require unique design and manufacturing. Using this guide to narrow down the list can help you determine the best plan for modification.

In case any requirement doesn’t fall in the range of standard options, skip it in the meantime to focus on the closest possible need for adjustment. So what should you be looking at for your solenoid purchase? Let’s get right to it.

Are you looking for a push or pull? This is where you begin narrowing down the candidate list by half. If you need a spring return, the push or pull is what you’ll be looking for. However, consider your expected spring return force, which we are going to discuss next.

Stroke Length and Force

Since these two characteristics are intertwined, we are going to deal with them in a single step. You can research online about force and stroke options to learn more about the two.

Remember, force curve comparisons can take up a lot of time during the selection process. Ideally, keep the manual comparison for later until you have completed the other procedures.

Duty Cycle

The duty cycle can be intermittent, continuous, or pulse. Make sure you choose the on/off cycle that is needed for your application. To understand the importance of duty cycle, ensure that you know exactly what your application will need to do and the way in which it is intended to work.

In this, as well as the next step, you may be realizing that you need to consider a more customized approach for your solenoids or reconsider a better strategy to achieve your goals.


For example, if you need to find the right miniature rotary solenoid, you’ll have to sort out any parts that seem too big to fit into your application. This is pretty much straightforward trait.

This is another distinct trait that is set to be tackled last since it’s easy to change. The most common voltages you may find are 12 and 24 volts. However, there are many companies that offer a wider range of voltages, from as low as 3 volts to as high as 30 volts.


This is an essential guide to help you find the right solenoid to work with. Follow these five steps from function, stroke length and force, duty cycle, to size and voltage for an easy way to figure out what you require.
