TW series
Hall effect thumbwheels
The TW series thumbwheel is a self centering single-axis device developed for thumb-actuated applications
requiring proportional output. Utilizing non-contacting Hall effect technology for long life performance, the
TW series thumbwheel delivers up to 5 million thumb actuations. Configuration options include choice of
linear voltage outputs as well as wheel colors. The TW series thumbwheel is available as a stand-alone
device or may be incorporated into one of our custom joysticks.
