Features: Base on the tunnel magnetoresistance effect, position is measured by detecting changes in magnetic field direction. Compared to the Hall effect, TMR have higher sensitivity and lower power consumption. Signal resolution is more than 10 times that of Hall. Not contact design, with seervice life equivalent to that of a Hall joysticks. High quality materials ensure long time use without wear and tear.
