The 890 Series Large Standard Grip Hand Grip Joysticks are specifically designed to control multi-axis machines in harsh, demanding environments where high quality, haptics and configurable sensors are required. Joysticks guarantee success in demanding applications with up to three axes.
It is often necessary to adjust the return behavior and spring force to suit the application. In the 890 series, the axle mechanics are made of metal and the axles 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 to return automatically to the center position via a spring (various spring strengths available) or to remain in its current position by integrating a friction brake.
- Optional lock positions (for the X and Y axes) can be used, e.g. to give the user a sense that the center position has been reached.
This allows the joystick sensitivity to be adjusted to suit a specific application.
For safety-critical applications, additional microswitches can be ordered that switch at a customer-specified deflection angle. Redundant switch configurations are also available.
The following microswitches are most often installed:
- Microswitch for center position detection (for x and y axes)
- Microswitch to detect 5°, 10° or 15° deviation (for x and y axes)
Potentiometers are typically used as the main angular deviation sensors in the 890 series because they are passive components and therefore immune to electromagnetic interference and electrical discharges. However, modern Hall effect sensors are also available which have the advantage of operating on the non-contact measurement principle and therefore exhibiting minimal deviation of the output signal during long-term operation. Both sensor options are available in a redundant version.
