Magnetic operating principles in combination with unique signal evaluation supported by powerful microcontrollers: These features make the new encoders from ifm electronic a real alternative to traditional photoelectric encoders. Thanks to extended, intelligent functions the new encoders are flexible for different applications in the field of motion control. The display, operating keys, and user-friendly parameter setting and diagnostics via IO-Link make them unique.
Three operating modes with the performance line
Firstly, they can be used as incremental encoders. The resolution between 2 and 10,000 pulses / revolution can be freely set. The units can also be used as counters. The direction of counting (up / down) and the switch points can also be selected. The third operating mode is used for rotational speed monitoring. The user sets a rotational speed range. The outputs switch when the current value is above or below the limit values. That means that the encoders operate automatically as rotational speed or standstill monitoring systems.
Display ensures a clear overview
All functions and parameters can be set on the unit via pushbuttons and LED display. During operation the current pulse, count or rotational speed values are displayed according to the set mode. The innovation: The two colours (red / green) show the user at once if the machine is in the acceptable range or if limit values have been exceeded. Furthermore the display can be rotated electronically by 180 degrees which allows flexible installation positions.
Another innovation: The parameters can be set not only directly on the new encoders but also in a user-friendly way via IO-Link. These options of communication ensure that the units are more than fit for Industry 4.0.
Practical use orientation
The high shock and vibration resistance enables use for applications in harsh environments. A practical detail: The cable entry or the rotatable M12 connection for connector units can be used both radially and axially. In the end the selection of the suitable encoder is reduced to the matching flange and the shaft - everything else can be freely configured by the user. ifm offers a basic version for users who use the unit as encoder and do not need the pushbuttons and the display. This version can also be set completely via IO-Link.
Conclusion
Extended functions, full IO-Link support and a reduced number of versions thanks to free configurability: Once again, ifm electronic sets new standards with the new encoders and makes the user fit for Industry 4.0.
