The HTWM offers the same performance as the standard HTW
Proportional Thumbwheel but with a much shorter behind panel
depth, ideal for use in grip, armrest and panel applications.
Available with eight output options, the HTWM offers a spring-
return-to-center, single axis thumbwheel actuator that provides
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 HTWM offers snap-in style
mounting and a three million cycle rotational life. The HTWM
electronics are sealed to IP68S and have excellent EMI/RFI
immunity.

* Outputs are from the center position to the full travel position in each direction. Options A–F provide increasing voltage in Direction 1 and decreasing
voltage in Direction 2 from a single output. Options G and H provide increasing voltages in both directions from two separate outputs.
** Options B and E provide redundant output 2 which duplicates output 1. Options C and F provide redundant output 2 which is inverse of output 1.
