Smallest magnetic measuring head for industrial applications

by Maximilian Schaffarczyk

The magnetic specialist BOGEN Electronic GmbH is presenting the extension of the X-class product series at Hannover Fair: the new micro-encoder X-IKS19. With this product, measurement solutions can be realized in the smallest possible space because the very small measuring head is arranged flat above the linear scale. The measuring head and scale can be implemented in a space of 20 mm length, 6 mm width and 5 mm height. This makes the X-IKS19 the smallest available magnetic measuring head for industrial applications. More functionality in a smaller space is required in many industries, such as electrical engineering, automation, mechanical engineering or robotics.

The X-IKS19 offers a resolution of up to 80 nanometers and, together with the X-class linear scales from BOGEN, a measuring accuracy better than 5 micrometers per meter. It has a digital ABZ interface, which is suitable for movement speeds up to 10 m/s and an output frequency up to 12.5 MHz.

BOGEN Managing Director Dr. Torsten Becker: "The market demands two points for magnetic measurement solutions: Higher accuracy and smaller size. The X-class measuring solution with the X-IKS19 fulfills these requirements and changes the performance spectrum of magnetic measurement technology. The X-IKS19 allows designers to create completely new solutions."

Due to the small dimensions of the X-IKS19 and the design freedom with magnetic scales, magnetic measuring systems can be realized where no measurement was possible so far. With the E2E (Engineer-to-Engineer) program, BOGEN will be able to advise customers of special measurement solutions in the future.

Technically, BOGEN's X-class encoders are based on pole pitches of 80 micron up to 500 micron. With a newly developed technique, the measuring heads read this pole pitch at a greater distance than before and reach system accuracies of 5 micron and better. This means that the accuracy of magnetic measurement systems reaches almost optical systems. Furthermore they are more cost-effective and – because of their insensitivity to dirt – more robust alternatives for highly accurate measuring tasks.
