Precise control in difficult conditions. TRY21 finger joystick

Economic angle measurement

Joysticks are now used in many devices, machines and vehicles for control. The demands placed on control devices are high: they must not only be sensitive and robust, but also fit well into the working environment. 

Finger joysticks provide the ideal human-machine interface. They ensure very high precision of operation because a person can control them with their fingers with exceptional sensitivity. This has contributed to the widespread use of medium-sized joysticks in industrial installations, but also in municipal and specialist vehicles and in medical technology. 

In safety-critical applications, signal errors or lack of control precision eliminate a component from use. Control panels for handling vehicles, mobile robots or unmanned systems require an interface that accurately translates the operator's movements into a control signal. The TRY21 industrial finger joystick from Megatron meets these requirements thanks to non-contact technology based on the Hall effect, as well as the compact size of the knob, which takes up very little space. 

Non-contact Hall technology – signal parameters and service life

The TRY21 joystick design uses Hall sensors, which eliminates the need for mechanical sliding contacts. This solution directly affects the electrical parameters and reliability of the component:

• High quality output signal - no mechanical wear eliminates noise and signal interference.
• Long mechanical life - sensors maintain linearity and repeatability of parameters throughout their entire service life.
• High sensitivity - the system immediately responds to minimal stick deflections, which enables precise navigation in difficult terrain.

Handling vehicles often work in dangerous zones, performing tasks such as removing unexploded ordnance or reconnaissance of the area during forest fires. The stability of the signal from the TRY21 joystick guarantees the operator full control over the machine's kinematics in such demanding environments.

Areas of application of the TRY21

Mechanical properties and a high degree of protection allow the joystick to be implemented in many advanced control systems. The component works well in applications such as:

• UAV control units: operator panels of fire brigade and police drones.
• Medical equipment: positioning systems in ophthalmic lasers, where micrometric accuracy of movement is required.
• Working machines: control systems for cranes and cranes, as well as municipal vehicles, such as sweepers.
• Measurement technique: precise setting of positions in laboratory test stands.

Security architecture and hardware customization

The design of the TRY21 model allows you to adapt the electrical and mechanical parameters to a specific engineering project. In systems where signal continuity failure poses a threat to health or property, it is possible to useredundant output signals. Doubling the measurement paths ensures continuous operation of the controller even if one of the circuits is damaged.

Megatron also supplies joysticks in versions with cabling modified to customer specifications. Matching cable lengths, cross-sections and connector types at the production stage speeds up installation in a control cabinet or operator panel and reduces the risk of assembly errors.
