US Digital Introduces New Addition to Miniature Optical Encoder Portfolio at ATX West 2017

Anaheim, California - February 8, 2017 - US Digital, a US manufacturer of quality motion control since 1980, today announced the introduction of the E8T miniature optical encoder. Combining small form factor and resolutions up to 720 CPR, the E8T is ideally suited for medical and other space sensitive applications that require reliable position and velocity feedback. The E8T's small package footprint fits motors as small as National Electrical Manufacturers Association (NEMA) size 11 with more than 40% reduction in package height compared to other commercially available solutions.

Utilizing US Digital's proprietary OPTO-ASIC technology, the newly announced E8T supports up to 2,880 pulses per revolution with excellent repeatability. The E8T is available in over 3,240 different configurations and features either single-ended or differential signal outputs. Moreover, the E8T features a simple and secure, push-on hub disk design and a high-retention connector for quick, easy and reliable installation that keeps assembly cost and complexity to a minimum.

Product Features

  • 9 resolutions up to 720 CPR
  • 3,240 configurations available, including single and differential output
  • Compact, low profile form factor
  •   1.120 inch (in) / 28.45 millimeter (mm) package outside diameter
  •   0.460 in / 11.68 mm package height
  •   Fits NEMA 11, 14 and 17 motors
  • Simple and efficient assembly process
  •   Four-piece construction
  •   Push-on hub disk design, patent pending
  •   High retention connector
  • 100 kilohertz frequency response
  • Functional replacement for US Digital's E7P and E8P

"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, Vice President 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."

US Digital Introduces New High Resolution E4T Optical Encoders at SPS IPC Drives 2016

Nuremburg, Germany - November 22, 2016 - US Digital, a US manufacturer of quality motion control since 1980, today announced the addition of 400 and 500 cycles per revolution (CPR) resolutions to its existing E4T line of miniature optical encoders. Specifically designed for robotics, medical and other industrial automation applications, the new E4Ts deliver position and velocity feedback, while fitting National Electrical Manufacturers Association (NEMA) motors as small as size eight.

Utilizing state of the art transmissive optical sensing technology, the newly announced 400 and 500 CPR resolutions represent up to a 38% increase in available CPR and now support applications requiring up to 2,000 pulses per revolution. This substantial increase in resolution was achieved without any compromise to package form factor, electrical characteristics or output signal robustness. The E4T line of encoders is available in both single ended and differential signal outputs for applications where noise immunity is critical. Moreover, the 400 and 500 CPR options retain the E4T's simple and efficient, push-on hub disk assembly process, helping US Digital customers keep installation time, assembly cost and complexity to a minimum.
