Rotary Encoders

Find rotary encoders online
By Ben Hahn, Freelance Writer Rotary encoders are angle transducers, tools that convert the angular position of a shaft or axle into an analog or digital code. Shaft encoders are used in industrial controls, robotics, photographic lenses, and a variety of other applications. A rotary relay can be either absolute or incremental. An absolute rotary encoder produces a single output code for every angle measured, while an incremental rotary relay can be programmed to deliver output based on line counts.

Measuring the output of a shaft encoder is an essential part of using these tools. An easy way to do this is with a rotary encoder USB that connects directly to your computer. Find a variety of options available from online suppliers to find the best rotary encoder product for your business:

1. Find a single source for a wide variety of absolute and incremental rotary encoder products.
2. Design a custom rotary encoder solution for your business.
3. Gain access to a rotary encoder circuit through your computer's USB port.
   

Find a manufacturer selling a wide variety of rotary encoders

If you want to compare products or aren't sure which product is best for your business needs, look to a manufacturer of a variety of rotary encoder products. Find a source of multiple products so you can easily compare rotary encoder spec information and determine which best suits your requirements without slogging through dozens of product listings.
Try:  SICK Stegmann sells both absolute and incremental rotary encoders. Find product specs and articles about rotary encoder technology on their website. AutomationDirect is a good source of low cost incremental rotary encoders and absolute encoders.

Contact a manufacturer of custom shaft encoders

There are a number of rotary encoder products on the market, but if you can't find one that fits your needs, or you have a situation that requires a rotary encoder to perform beyond the standard, work with a manufacturer of custom rotary encoders.
Try:  Immersion can help you design customized rotary encoder solutions for an array of industrial applications. Use the product inquiry form on their website to contact them about a custom solution. Netzer Precision is a worldwide distributor and manufacturer of rotary encoders for applications ranging from avionic to automotive. Visit their website for information on standard products or to request a custom rotary encoder.

Buy a USB rotary encoder

An important aspect of any rotary encoder device is the ability to measure and read the coded output from the tool. You do most of your business on a computer, so it makes sense that the easiest way to view data would be on your computer. For ease of data interpretation, look for a rotary encoder that you can easily hook up to your PC's USB port.
Try:  US Digital offers a rotary encoder data acquisition device that can connect to eight rotary relays and comes with easy to use Windows software. RobotShop specializes in rotary encoders used in robotics, and sells a number of products for encoded data capture, including the Phidgets USB Rotary Encoder.

• Shop around when you're looking for a manufacturer of custom rotary encoders. Request price quotes from multiple suppliers before making a choice so you know you're making the best deal for your company.
