US Digital Introduces New High Resolution E4T Optical Encoder Now with 400 and 500 CPR

Vancouver, Washington - 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 2000 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.


Product Features:
• 10 resolutions up to 360 CPR, plus new 400 and 500 CPR resolution
• 288 configurations available, including single and differential output
• Compact form factor
o 0.866 inch (in) / 22.00 millimeter (mm) package outside diameter
o 0.446 in / 11.33 mm package height
o Fits NEMA 8, 11, 14 and 17 motors
• Simple and efficient assembly process
o Four-piece construction
o 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."

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
