Live Electronics Ltd supply a range of Hall Effect Joystick, Rotary Switches and Sensors from companies such as Ruffy Controls, Elma and ZF.
Hall Effect joysticks allow for great variation from single axis paddles to miniature 4way finger-controlled joysticks that give repeatable accuracy, exceptional return to center voltages and the ability to have pre-programmed outputs in analog, CANbus, and USB or for custom outputs to be created. Elma’s X4 is a new style of rotary switch that can be used as an incremental encoder or an absolute coded switch, Live Electronics also carry a range of speed, direction and linear sensors from leading manufacturer ZF.
Hall Effect controls allow cycle lives between 1,000,000 and 15,000,000 cycles! All while giving the user greater feel and perception. The great variety of components that are now available in Hall Effect are allowing designers the freedom to create small, long lasting and above all reliable products that are perfect for Military, CCTV, Construction and Agricultural Vehicles, Conveyor systems, Robotics and ROV Control and Wheelchair Operation.View Frequently Asked Questions about Hall Effect

The Hall Effect principle is that when a current is passed in one direction through a conductor and a magnetic force is introduced perpendicular to this, the magnetic field moves the electronics within the conductor creating a voltage change. You can then measure the change in voltage by taking a reading at right angles to the currents path, this measurable voltage is the Hall Effect.
Hall Effect is important within electromechanical devices as it allows for the accurate positioning or sensing of mechanical devices such as joysticks or gear tooth speed sensors. The main advantage of Hall Effect devices is that they are immune to dust, dirt and water and due to their frictionless operation they have extremely long electrical lives.
Hall Effect measure the change in voltage across a conductor where a current is been passed whilst a magnetic field is been introduced via magnets perpendicular to the conductor.
The Hall Coefficient is represented mathematically by RH and is 1/(qn) where q = charge and n = number of charge carriers per unit volume. The Hall Coefficient can be either positive or negative.
Hall Effect sensors are very reliable and robustly built however they can fail due to physical or electrical damage. Physical damage can usually be seen visually such as the casing being cracked or dented due to a heavy impact. Electrically the input voltage can be incorrect, or damage could have happened to the internal wiring due to being dropped etc. They can also malfunction if they are not set up within the device in an optimal way eg. too far away from the gear teeth in a gear tooth speed and directional sensor.
