3 MILLION CYCLE ROTATIONAL LIFE
The HTW Hall Effect Proportional Output Thumbwheel is a self-
centering, single axis thumbwheel with an actuator that
provides linear change in voltage output in either direction
from the center. Available with eight output options, including
increasing and decreasing voltage output from the center
position to the full travel position and single or dual (redundant)
outputs. The HTW snaps into a 1.47” x 0.710” panel opening
with rocker switch style mounting. A durable switch providing
3 million cycle rotational life, sealed to IP68S and excellent EMI
immunity per MIL-STD-46 ID/SAE J1113-22, and will withstand
RFI of 100V/M 14Hz to 1GHz.
