A two axis non-contacting displacement precision hand operated control with grip, the Model 502C utilizes Ultra MSI’s patented Hall effect technology.  Providing high performance and high reliability results at a low cost, this technology has revolutionized the HMI (Human Machine Interface) industry.  

First patented and introduced by Ultra MSI in 1998 (U.S. Patent No. 5850142), these devices offer many benefits over traditional potentiometer and inductive joystick designs. Principally no wearing parts and hence exceptional life and stability of output. In particular the accuracy of the zero position is outstanding in the Ultra MSI joystick design.
