Before we get to the heart of how they are being used, let us first talk about what rotary position sensors are. Rotary position sensors are a type of position sensors that can measure the change in the angle of a particular object which the sensor then converts into a change in the output voltage.
Being able to change the output voltage in relation to a change in position of a certain object as a stand-alone fact will not make you appreciate the importance of rotary position sensors. But when you take a look at its many different industrial applications, you will see just how important it is. It’s not the only sensor there is, but it is one of the most durable because of its characteristics.
What are the industrial uses of rotary position sensors? They are being used in small engines, robotics, medical equipment, test and measurement equipment, and consumer electronics. And there are other uses, for example, there are certain models of rotary position sensors that are designed for use in throttle and gear position control in motorsports. The same sensors are used in steering angle measurement as well as in the chassis monitoring system.
In general though, they are used providing position feedback, which is very important in monitoring. Because of this general industrial application, you might just find that this simple-looking sensor has many other applications aside from the ones mentioned here.
Rotary position sensors use a low-force multiple electrical contacts for monitoring objects, which is ideal for instruments that experience a severe vibration in one single position for a long period of time.
If you search for it online, you will see that there are many manufacturers of this type of sensor. But if you are like most people, you will never have a need for this product, unless if you are making an end-product that has a monitoring and measuring component to it.
In any case, not all rotary position sensors are created alike and you will see that the different sensors on the market are made to different electronic sensing angles and sealing. If you ever have a need for these products, make sure to look at the specs. You can look for more information by searching for “rotary potentiometer” on Google, there are plenty of interesting sites.
There are manufacturers out there that allow you to customize their product based on certain parameters. Definitely, if you need to have sensors made to a certain specification, you will want to deal with these manufacturers.
Just as there are many different companies that make them, you will find that there are different types of the same rotary position sensor. These types are analogue, absolute multi-turn modular, magnetic CANopen, and multi-turn modular. If these classifications do not make sense to you, welcome to the club. There are many people just like you, however, you can easily get information on them by doing a quick search on Google. Again, if you need to have them customized, you can, just contact the manufacturers with your specifications.
