Product Details

Otto HTWF Series - Hall Effect Thumbwheel

The HTWF Hall Effect friction thumbwheel offers a maintained position, single axis thumbwheel actuator that provides a 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 HTWF thumbwheel has a rocker style snap-in mount that accommodates a 1.47 x 0.710” panel cut-out. The HTWF provides 250,000 cycle life, full forward/full backward, is sealed to IP68S and offers excellent EMI/RFI immunity. Ideal for heavy equipment, industrial machines or remote control applications.
