# What are the advantages of Balluff's absolute measuring system with IO-Link?

## Magnetic encoder system, BML SL1

The BML SL1 absolute measuring system stands out in any application where high  
absolute accuracy of current and limit positions is required. It was developed for  
measuring and positioning applications in any industry, and combines the advantages  
of a magnetic encoder system with the most innovative interface in the automation  
world.

An optional analog interface is available for control applications. IO-Link offers parameterize and diagnostic functions including condition monitoring of the measuring system.

 

When other measuring systems are too large, too slow, too imprecise or too inflexible, you can count on the BML SL1, and benefit from the simple connection to IO-Link systems. Whether linear or rotary motion, position or angle measurement, format changes, short or long distances – this system is a simple and economical solution for countless applications.
