HALL EFFECT CONTROLS HTWS SUBMINIATURE PROPORTIONAL OUTPUT THUMBWHEEL THUMBWHEEL SUBMINIATURE PROPORTIONAL OUTPUT THUMBWHEEL The HTWS Hall Effect Proportional Output Thumbwheel is a smaller version of OTTOs HTW and HTWM. It is a spring return- to-center, single axis thumbwheel that provides a linear change in voltage output corresponding to actuator movement in either direction from center. Its smaller size makes it a perfect choice for use in grips or panels where space is limited. The HTWS is Knurled Wheel Paddle Wheel available with eight output options, including increasing and decreasing voltage output from the center position to the full Standard Characteristics/Ratings: travel position and single or dual (redundant) outputs. ELECTRICAL RATINGS: Rated at 5V 25C Load = 1mA (4.7K) The HTWS snaps into a 0.895 x 0.420 panel opening. Electrical Units Min Typ Max Electronics are sealed to IP68S, and an optional sealing boot Supply Voltage VDC 4.5 5.0 5.5 is offered for added protection against dust, sand, and water Output Voltage VDC -.25 N/A +.25 ingress. The HTWS offers a three million cycle rotational life, Tolerance at Center 5V Vcc operate force options and excellent EMI /RFI immunity. It is Output Voltage VDC -.25 N/A +.25 available with flying wire leads or pin connection.
