OTTO HTW Hall Effect Thumbwheel

Hall Effect Thumbwheel, Rocker Switch Style Mounting.

The OTTO 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 /RFI immunity. The HTW Hall Effect Proportional Output Thumbwheel works well in numerous commercial applications.
