US Digital, a motion control manufacturer, recently announced the release of its E8T miniature optical encoder.

Combining small form factor and resolutions up to 720 CPR, the E8T is best suited for medical and other space-sensitive applications that require reliable position and velocity feedback. The E8T fits motors as small as National Electrical Manufacturers Association (NEMA) size 11, with more than 40 percent reduction in package height compared to other commercially available solutions, according to US Digital.

Using the company’s proprietary OPTO-ASIC technology, the E8T supports up to 2,880 pulses per revolution. 

The E8T is available in over 3,240 different configurations and features either single-ended or differential signal outputs. It also features a push-on hub disk design and a high-retention connector for quick installation to keep assembly cost and complexity to a minimum.

“Whether its portable technology or diagnostic equipment destined for the laboratory floor, today’s medical applications face increasing pressure to become smaller and lighter without compromising functionality,” said Donna Peterson, VP of marketing and sales at US Digital.

“The E8T’s small, low profile package and available resolutions make it uniquely positioned to help address these requirements while delivering excellent value and reliability relative to alternative motion control solutions.”

Sample and production quantities of the E8T are now available. To learn more about the E8T miniature optical encoder, visit the US Digital website.
