Thumbwheel Switches

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. Hall Effect contact-less sensing technology Maintained control positioning, no return to centre Rocker switch style mounting, snaps into 37.33 x 18.03mm panel cut-out Behind panel depth: 35mm Operating force: 0.25lb Black bezel and wheel IP68 sealed Excellent EMI/RFI immunity Pre-wired version is terminated with 450mm long 18AWG wires with stripped ends Pin version is terminated with 0.635mm square pins Detent option available (see stock number 737-3768 ) Additional Info Stk No. Manufacturer Part No. Termination Output1 Output2 Dentent 737-3765 HTWF-1A12B22 Pins 2.5 ±2.0 Vdc N/A N/A 737-3768 HTWF-1H11A22A Wired 0.5 - 4.5 Vdc 0.5 - 4.5 Vdc Detent 2oz increase out of centre in both directions.
