Courtesy: HeidenhainHeidenhain's ERO 1200/1400 series of modular optical rotary encoders without integral bearing are non-contact and well-suited for motion control use on dynamic stages and machines in the general automation or semiconductor industries, such as a pick and place machines. They are also used on air bearing spindles, blood pumps, and servo motors in robotic applications.

With onboard interpolation, the ERO 1400 can achieve resolutions of 37,500 signal periods per revolution, facilitating use on high-resolution viscosimeters or portable mass spectrometers.

The bearingless design help allow axial motion up to ±0.02mm, providing room for thermal growth of motors or machines. This encoder series supports line driven TTL outputs (RS422), as well as differential one volt peak-to-peak signals, which can be interpolated for use in a speed control loop.

With through-shaft diameters of 4, 6, or 8 mm, and a self-centering slide mechanism, the ERO 1400 is a small, versatile encoder with onboard interpolation and easy mounting. The ERO 1200 is available with a 10 mm or 12 mm shaft, offering a graduation accuracy of ±6 arc seconds.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
