The large Hand Grip Joysticks of the 890 series with stock grip handle have been specially designed for multi-axis machine control in harsh, demanding environments where quality, haptics and configurable sensors are required. The joysticks are a guarantee of success in demanding applications with up to three axes.
It is often necessary to adjust the return behaviour and spring force to suit the application. In the 890 series, the axis mechanics are made of metal and the axes are designed with separate shafts for the X and Y axes. This allows the sensors for each axis to be configured largely independently:
- The joystick handle can be configured either to return automatically to the centre position via a spring (various spring strengths available), or to remain at its current deflection by integrating a friction brake.
- Optional lock positions (for x- and y-axis) can be realized, e.g. to give the user the feeling that the centre position has been reached.
This allows the joystick feel to be tailored to the application.
For safety-critical applications, additional micro switches can be ordered to switch at a customer-defined deflection angle. Redundant switching configurations are also available.
The following microswitches are commonly fitted:
- Microswitch for detecting the centre position (for x- and y-axis)
- Microswitch for detecting 5°, 10° or 15° deflection (for x- and y-axis)
Potentiometers are normally used as the main sensors for measuring angular deflection in the 890 series, as they are passive components and therefore immune to electromagnetic interference and electrical discharge. However, modern Hall sensors are also available, which have the advantage of a non-contact measuring principle and therefore show minimal drift in the output signal over long periods of operation. Both sensor options are available in a redundant version.
