HTWF PROPORTIONAL OUTPUT THUMBWHEEL HALL EFFECT THUMBWHEEL FRICTION ACTUATION STYLE THUMBWHEEL Standard Characteristics/Ratings: MECHANICAL: Mechanical Life: 250,000 full forward to full back with center detent Initial Operating Force at Top of Roller: 2 oz min to 6 oz max @ 25C Max Allowable Radial Load: 30.0 lbs. Paddle Wheel Style Drop: 3 feet max to concrete ELECTRICAL RATINGS: Rated at Vcc = 5V @ 25C Load = 1mA (4-7K) Knurled Wheel Style The HTWF Friction Thumbwheel offers a maintained position, single axis thumbwheel actuator that provides a linear change in voltage output in either direction from center. Options include increasing or decreasing voltage output from the center position to the full travel position, and single or dual (redundant) outputs per axis. The HTWF Thumbwheel has a rocker style snap-in mounting feature to accommodate a 1.47" x 0.710" panel opening. The HTWF provides 250,000 cycle life, full forward/full backward, is sealed to IP68S and offers excellent EMI/RFI immunity and a flow through design. Ideal for heavy equipment, industrial machines or remote control applications.
