Knee control unit XENOX-Dent 50s

The knee control unit's electronics

controls the brushless motor of the handpiece, adjusting the speed and torque, and responding in the event of a malfunction (blocked motor or overload). Digital display for speed and error code messages. Connection socket allows for fitting the optional foot pedal (NO 67 050). Practical fastening rail for fixing the control unit beneath the work bench.


Easy to read and self-explanatory. High-quality coated front label with detergent-proof surface and permanent marking.


The required maximum speed is pre-selected on the adjusting knob. For safety reasons this rotational knob has a locking key that must be pressed, if speeds over 40,000rpm are required. The knee-activated lever or the foot pedal infinitely control the speed up to the pre-selected maximum speed.

Activatable speed control function

If the speed remains constant for 3 seconds during operation via knee-activated lever or foot pedal you will hear a beep. Thereafter the "working speed" does not change, even if the knee-activated lever or foot pedal is no longer operated. This function is deactivated, as soon as the knee-activated lever or foot pedal are pushed again.
