The HTWF Friction Thumbwheel offers a maintained position,
single axis thumbwheel actuator that provides a linear change
in voltage output in either direction from center. Options include
increasing or decreasing voltage output from the center position
to the full travel position, and single or dual (redundant) outputs
per axis. The HTWF Thumbwheel has a rocker style snap-in
mounting feature to accommodate a 1.47” x 0.710” panel opening.
The HTWF provides 250,000 cycle life, full forward/full backward,
is sealed to IP68S and offers excellent EMI/RFI immunity and
a flow through design. Ideal for heavy equipment, industrial
machines or remote control applications.
