HTWF PART NUMBER CODE
HTWF X X X X X X X X
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.
Features:
250,000 cycle life, full forward/full backward with
center detent
Maintained control positioning, no return to center
Hall Effect contactless sensing technology
Number of output options
Choice of bezel & button colors
Snaps into 1.47” x 0.710” panel opening
Electronics sealed to IP68S
Excellent EMI/RFI immunity
* Output options A–F do not
have a tolerance on the
center outputs unless
a center detent is selected.
Output options G & H are
only available with
center detent.
