OTTO HTWF Hall Effect Friction Actuation Thumbwheel Range Details

Part of the OTTO Hall Effect Controls, these Rocker Style Thumb Switches feature a single axis, with friction hold actuation. OTTO HTWF Rocker Thumbwheel Switches provide a linear change in voltage output, with options to increase or decrease voltage output. KEY FEATURES • Friction Hold Switches • Custom Options • EMI/RFI & IP68S Rating The OTTO HTWF Hall Effect Thumbwheel provides a long cycle life - Ideal for heavy equipment, industrial machines or remote control applications.


OTTO HTWF HALL EFFECT FRICTION ACTUATION THUMBWHEEL

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.
