Small, low cost absolute magnetic encoder for different measuring lengths

by Nicole Winzer

With BOGEN´s AKS17 magnetic encoder linear absolute measurement applications can be implemented from 100 mm up to 3 m in length with a resolution < 1 µm. For rotary applications, diameter from 100 mm up to 1 m in diameter lead to a resolution of up to 24 bits. The high resolution allows to use magnetic encoders, where optical solutions are expensive to implement. At the same time, there is a lot of design freedom in the scales as the pattern can be adapted to different segment requirements.

With this variability the AKS17 and its corresponding scales can be used in nearly any automation application where absolute measurement is necessary. The size of the AKS17 is 28 mm in length, 16 mm width and a height of either 3.4 mm or 6.6 mm. Due to these dimensions the AKS17 can be implemented even in automation applications which require a space-saving measurement system.

The AKS17 provides BISS-C or SSI as an output as well as an incremental quadrature signal. This allows to start with an incremental measurement and after an update of the control system the use of absolute information without a change in encoders. Or the system can use the absolute information at startup and provide an incremental signal during operation. 

For just incremental measurement BOGEN offers the encoder IKS9. The IKS9 impresses with a system accuracy better than 8 µm and a resolution down to 20 nm. Digital quadrature signals can be supplied, the sister product IKS15 provides an analog output signal. Due to easy configuration of numerous parameters the IKS9 can be adjusted to many customer-specific requirements.

BOGEN’s managing director Dr. Becker stresses: “AKS17 and IKS9 magnetic encoders are used in harsh environments as the have the IP67 protection class. Thanks to magnetic technology all BOGEN measurement solutions are resistant to contamination and robust to vibrations – and thus maintenance-free and cost-efficient. The AKS17 offers a cost efficient absolute magnetic measurement solution – many companies are surprised that absolute measurement can be achieved with such a low price.”

Whether it is positioning, motion control or monitoring within the automation system - the basis for automation technology is always a highly accurate and reliable measuring technology. It is used to control the rotary speed of motors, to determine the position of axes, to position linear stages, or to control robots. BOGEN Electronic GmbH offers the right magnetic measuring solution for all these applications.
