Electronic Cam-Operated Switch Group PAX
Complex mechanical switch controllers?
Cam switch controllers are used
wherever control is required rel-
evant to the machine position.
With mechanical cam switch
controllers, and particularly with
rotational movements, mechani-
cal cams are positioned on a
shaft. These cams must be intri-
cately positioned according to
their switching characteristics in
order to actuate the mechanical
switches for drive shift rotation.
There is an easier option!
The electronic cam-operated switch group PAX provides a far easier al-
ternative. The position of the drive shaft is detected using a wear- and
maintenance-free PMI inductive rotation angle sensor and is transferred
as an absolute value to the robust PAX box.
A PC and USB interface can be used to parameterize individual switching
windows, trip points, or switching ramps in the cam switch controller. The
ewasy-to-use software is integrated into the PAX and starts automatically
when a PC connection is established. Up to 12 switching outputs each
with 250 mA, two power outputs each with 2.5 A, and six analog power
outputs (4 mA ... 20 mA) can all be individually configured and activated
in the PAX.
All the data and parameters are stored on a micro SD card that is inte-
grated into the cam switch controller and that can be easily removed and
reinserted. This micro SD card also contains the configuration software.
No installation is required on the PC.
