Baumer Magnetic encoders there Series EAM580 / 360 work particularly reliably and precisely. The magnetic Absolute encoders work with an angular accuracy of ± 0,15 degrees and thus enable precise positioning in the application.

"No competitor product with comparable robustness and durability can reach the EAM580 / 360 in terms of absolute angular accuracy," emphasizes Daniel Kleiner, Head of the Industrial Encoder Business Unit. According to Kleiner, with this generation of robust magnetic encoders Baumer emphasizes precision in terms of a dimension that was previously reserved for optical encoders. »The series also offers the integration of efficiency-enhancing interfaces.

Patent pending double magnet arrangement

The secret behind the high precision and robustness of the Baumer encoders lies in the patent-pending double magnet arrangement and the interaction with a powerful, energy-efficient microprocessor as well as sophisticated signal processing algorithms for the conversion, filtering and interpolation of the measured values. "Magres" encoders use magnetoresistive (MR) technology. This provides two signal periods per revolution and thus twice as many as the Hall sensors, which are usually used in the encoders of other manufacturers. And all this Baumer has packaged shock and vibration resistant.

When developing the EAM series, the sensor specialist benefited from the fact that the company not only co-invented the basic principles of magnetic encoders, but that the company has been working very successfully in this field for two decades now and the Magres encoders are already working in the 4. Generation gives. Due to their high accuracy, the encoders are even suitable for use in medical devices. For example, in patients' recliners of X-ray machines and CT scanners, they ensure the exact positioning of patients during treatment. Because here, the fraction of an angular degree can be decisive for the success of the treatment. But even with countless applications from industry, the precision of the EAM 580 / 360 encoders determines "how efficiently and effectively the entire application works".

In addition to numerous fieldbus interfaces, Baumer also offers the highest variance of real-time Ethernet interfaces such as Profinet, EtherCAT and Ethernet / IP. This greatly simplifies device integration for the users. Above all, however, Link Layer Discovery Protocol (LLDP) for proximity detection and Media Redundancy Protocol (MRP) or Device Level Ring (DLR), which secure the transmission of data to the controller even if it is interrupted in one branch of the network, are increasing, among other things. the availability of the facility.

OPC UA standard for the Internet of Things

The OPC UA communication standard is also supported. This ensures a feedback-free and secure data exchange between different systems. The open and platform-independent standard can also be easily adapted to future requirements. This equips the EAM580 / 360 encoders with the requirements of the industrial Internet of Things (IIoT). If necessary, they diagnose data such as position, speed, temperature and operating hours. This allows users to optimize their processes and improve the design of machines and systems.

  • User report Food and beverages In view of ever more individual customer requests and smaller lot sizes in high-wage countries, manufacturers can only remain competitive with sufficient process automation. High-performance and robust sensors are required here so that the systems become transparent. The Swiss sensor experts from Baumer work closely with their customers to create the right automation for their problems.
  • Sensors that deliver reliable and precise measured values ​​can create real added value with IO-Link. For greater flexibility, Baumer presents its sensors using the dual channel principle. The PP20H pressure sensor and the Combilyz AFI conductivity sensor from Baumer now offer even more interesting functions with the IO-Link interface. For example, they can be parameterized quickly and easily - even during operation. Thanks to the dual channel, the sensors can be operated simultaneously, digitally or via the respective channel.
  • With the fully digital inductive IO-Link sensors Alphaprox from Baumer the most extensive diagnostic data on the market can be generated. In addition to sensor temperature, operating time and operating voltage, the IO-Link sensors also record boot cycles, switching frequency and distance values. This information can easily be called up via the IO-Link interface and digitally processed in the controller. In addition, the sensors have a kind of memory.
  • The new smart “Verisens” XF900 and XC900 vision sensors from Baumer control the collaborative robots (cobots) from Universal Robots after just a few minutes of setup. The robot-compatible vision sensors are mounted directly on the cobot or above. Calibration with regard to image correction, conversion to world coordinates and coordinate comparison between the vision sensor and robot is carried out automatically and very easily thanks to the patent-pending Smartgrid.
