The HTWF Friction Hold 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.
