Product Details

Otto HTW Series - Hall Effect Thumbwheel

The HTW Hall Effect proportional output thumbwheel is a self-centre, single axis thumbwheel with an actuator that provides linear change in voltage output in either direction from the centre. Available with four output options, including increasing and decreasing voltage output from the centre position to the full travel position and single or dual (redundant) outputs. The HTW snaps into a 1.47 x 0.710” panel cut-out 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.
