Williams Controls WM-531

Remote Sensor Control, Shaft Hand Control.

The WM-531 Shaft Hand Control is built for a range of off-highway applications. The unit is designed for remote installation and mechanical interface with a throttle position sensor. It is infinitely variable between 0° and 54° with applicable uses that include engine RPM and chassis module outputs. The Remote Sensor Control unit is equipped with a Hall effect, non-contact sensor that can be programmed for analog output and/or integrated switches. The electronics are IP67 sealed and highly EMI resistant (SAE J1113). In addition, the remote sensor control unit can be customized with contact or PWM sensors. The Remote Sensor Control is environmentally protected, allowing it to be mounted inside or outside the cab. It is made out of aluminum with stainless steel shaft.

The unit is available with two shaft designs: knurled and D-shaft.
