What is hall effect?

If an electric current flows through a conductor in a magnetic field, the magnetic field exerts a transverse force on the moving charge carriers which tends to push them to one side of the conductor. A buildup of charge at the sides of the conductors will balance this magnetic influence, producing a measurable voltage between the two sides of the conductor. The presence of this measurable transverse voltage is called the Hall effect after E. H. Hall who discovered it in 1879.

Applications for hall effect sensing have also expanded to industrial applications, which now use Hall effect joysticks to control hydraulic valves, replacing the traditional mechanical levers with contactless sensing. Such applications include mining trucks, backhoe loaders, cranes, diggers, scissor lifts, etc.

As the need for joysticks increases designers are undergoing greater pressure to achieve use requirements while also cutting down cost. These requirements include but are not limited to sensitivity, accuracy, low power, smoother operation, custom install size, and multi-function features. It is particularly important in industrial environments where proper control of heavy equipment is critical to prevent work related injuries or loss of productivity.

CGEC has custom developed several types of industrial electric joysticks to serve Original Equipment Manufacturers (OEMs) and operators across industrial, commercial, and consumer environments. When focusing on industrial applications, joysticks for machines and equipment play a crucial role. For this reason, it’s important to be familiar with two of the leading types of industrial joysticks: hall effect joysticks and potentiometer joysticks.

Hall type joystick features:

l  Hall non-contact angle detection

l  long lasting

l  High pollution resistance

l  The trend in future

l  Power is 5V, 9~36V is possible.

Except FJ120 series joystick,all joysticks can be made into hall type.
