The HTW Hall Effect Proportional Output Thumbwheel is a
spring-return-to-center, 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 three
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.
