Wide range of haptic feedback

through MRFtechnology

The use of magnetorheological fluid (MRF) allows the imple

mentation of improved use cases on the HMI. The response

speed of the MRF technology makes various feedback pat

terns, such as ripples, blocking or torque levels possible. As

a result, different mechanical properties can be combined in

just one operating element.

The opportunities of this new patented technology comprise

KeWheel modes such as overrides for rapid traverse, for

ward feed, spindle, different handwheels, user interface input

options, hold to run buttons, and many more. The KeWheel

and all its functions can be easily integrated via a real-time

fieldbus, such as PROFINET.

Anyway, to cut a long story short –

you need to feel this!
