ifm efector intelligent encoders

Click2Contact

A range of intelligent encoders has been released by ifm efector. They can be used as incremental encoders, with a resolution of between 2 and 10,000 pulses/revolution that can be freely set. The units can also be used as counters, with the direction of counting (up/down) and the switch points selectable.

The third operating mode is used for rotational speed monitoring — the user sets a rotational speed range and the outputs switch when the current value is above or below the limit values. The encoders can therefore operate automatically as rotational speed or standstill monitoring systems.

All functions and parameters can be set on the unit via push-buttons and the LED display. During operation the current pulse, count or rotational speed values are displayed according to the set mode. Two LED colours (red and green) immediately indicate if the machine is in the acceptable range or if limit values have been exceeded. Additionally, the display can be rotated electronically by 180°, giving flexible installation positions. The parameters can also be set via IO-Link.

High shock and vibration resistance enables use for applications in harsh environments. 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.
