Otto HTWM Series - Hall Effect Thumbwheel
The HTWM offers the same performance as the HTW proportional thumbwheel but with a much shorter behind panel depth. Available with four output options, the HTWM offers a self-centre, single axis thumbwheel actuator that provides linear change in voltage output in either direction from centre. Options include increasing or decreasing voltage output from the centre position to the full travel position, and single or dual (redundant) outputs per axis. The HTWM offers snap-in style mounting and a 3 million cycle rotational life. The HTWM electronics are sealed to IP68S and have excellent EMI/RFI immunity ideal for use in grip, armrest and panel applications.
