The BML SGA series absolute magnetic encoder from Balluf is, according to the company, the ideal candidate for any application requiring high precision in absolute position measurement or limit switch detection. A comprehensive set of diagnostic functions ensures reliable operation and easy maintenance. Thanks to its Drive-Cliq interface, the Balluff displacement measurement system can be perfectly integrated into environments using Siemens controllers. It also benefits from Siemens certification.
The "plug-and-play" installation facilitates integration into the axis control. The controller automatically detects the sensor and its basic parameters. The sensor offers a very great functional flexibility, since it can be moved away from the coded tape, and then resume detection by simply bringing it closer to the tape. This opens up possibilities that are both simple and economical for certain demanding applications in the field of automation and the construction of machine tools, especially special machines.
The system uses a magnetic detection principle. It is totally insensitive to temperature variations, to dirt (dust or grease), and to wear. Thanks to its compact size, this measuring system is very easy to integrate into existing applications, even if there is little space available. The generous reading distance (up to 1.3 mm) facilitates implementation.
The consistency of the measurements is checked continuously during operation, which guarantees very high reliability. Automatic monitoring of signal quality by the controller is a good way to assess functional robustness.
LED status indicator and diagnostic functions ensure reliable operation and easy maintenance.
This linear measuring system is suitable for measuring large displacements (up to 48 meters) as well as for applications requiring high precision. With an accuracy of up to ± 12 µ and a resolution of 1 µ, the system meets these needs. This displacement measurement system is also easy to retrofit.
