Amidst speculation in the motion control community, Heidenhain Corp., the German-based encoder company, confirms that it is closing in on a U.S. launch date for a new line of products featuring an all-digital, bi-directional serial interface. "By 2005, there should be several products available, starting with a linear scale in mid-2004, followed by angle and rotary encoders," says Product Manager Tom Wyatt. The high-speed serial interface, known as EnDat 2.2, follows EnDat 2.1, which was introduced 8 years ago. The availability of a purely digital encoder interface has enormous implications for motion control engineers, who will be able to take advantage of clock frequencies of up to 4 MHz over cable lengths up to 100m. Further, position encoders with this type of interface will be able to transmit data, including position data and other parameters, in either direction. "We wanted to give engineers the luxury of having absolute feedback without having to sacrifice speed," Wyatt explains. He says that the products will be backward compatible with the existing 2.1 technology, and that the company plans to offer the EnDat 2.2 for the same price as EnDat 2.1.

Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
