US Digital’s E4T line of miniature optical encoders is available with 400 and 500 cycles per revolution (CPR) resolutions. Specifically designed for robotics, medical and other industrial automation applications, the E4Ts deliver position and velocity feedback, while fitting National Electrical Manufacturers Association (NEMA) motors as small as size eight.
Using state-of-the-art transmissive optical sensing technology, the 400 and 500 CPR resolutions represent up to a 38% increase in available CPR and support applications requiring up to 2,000 pulses per revolution. This 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.
Key features include the following:
- 10 resolutions up to 360 CPR, plus new 400 and 500 CPR resolution
- 288 configurations available, including single and differential output
- Compact form factor
- 0.866 in. (22.00 mm) package outside diameter
- 0.446 in. (11.33 mm) package height
- Fits NEMA 8, 11, 14 and 17 motors
- Simple and efficient assembly process
- Four-piece construction
- Push-on hub disk design, patent pending
- 100 kilohertz frequency response
- Shafted version up to 0.25 in. (6.25 mm) diameter
“Industrial automation has become smaller, faster and more prevalent in today’s engineering fields, and with developments in collaborative robotic technology, as well as medical device development, human safety and practical reliability are more important than ever. Simultaneously, system developers have expressed an increasing demand for smaller form factors and more precise motion control,” said Donna Peterson, Vice President of Marketing and Sales at US Digital. “The higher resolution, compact E4Ts directly address these requirements, while broadening US Digital’s extensive line of quality motion control solutions.”
