Miniature thumbwheel

  • 17-Jun-2009 09:14 EDT

Elobau Sensor Technology’s 175D miniature thumbwheel is an illuminated device based on Hall-effect technology that can be incorporated in the knob of a joystick, a multifunctional handle for a shifter, or a control panel. The control provides two output signals that can be combined in eight different options, including 0.5- to 4.5-V ratiometric outputs proportional to the rotation of the thumbwheel, and switching outputs. It provides an accurate proportional control of auxiliary functions. Typical applications include control panel, armrest, shifter, single- or dual-axis joystick, or any control panel application on industrial equipment, remote control, mobile equipment, or machinery. The illumination allows the operator to identify clearly which function is activated, even in the presence of adverse lighting conditions. Illumination is provided by three different LEDs or one multifunction LED that will switch colors when the function is activated. Available colors are red, green, white, yellow, orange, and blue. Noncontact sensing ensures longer service life, and the device operates from -40 to +85°C (-40 to +185°F).
