    Absolute Feedback Systems for Efficient Drives

The BML series from Balluff offers rugged, precise and quick absolute position and angle measurement systems, which are ideal for installation or direct integration into drive and positioning systems. The new, magnetically encoded absolute position and angle measurement systems with Permagnet nonius technology close a gap in the segment of compact, integrative, absolute measurement systems with IP 67 housing for external installation. As an open kit for full integration, they now have the option of being used in rotary applications as well. Using these systems, the formats, strokes and end positions of axes can be adjusted automatically, quickly and reliably. The new absolute encoder disk can be integrated easily into motors and actuators as a highly precise, absolute feedback solution. Because of this, it is an efficient alternative to conventional magnetic or optical solutions for accurate control of motors and drives. The low space requirement for the solution for rotary applications provides another eye-catching quality; it is just 12 - 20 mm in length and 30 mm in diameter depending on the design.

A fully integrated, single-chip solution is the core of the magnetic scanning and signal generation process. The position data is generated in real time and made available in absolute form using interfaces typical in drive engineering, SSI or bidirectional BiSS C. Incremental SIN/COS analog signals and ABZ signals are also on hand for use.
