ALMAX introduces The MaxRotor®, a non-invasive, low-profile encoder that allows for a more diverse array of keypad design options. As the only rotary switch that can be mounted directly to a flexible circuit, the MaxRotor®, makes design integration easier than ever.  Expanding thin-panel design possibilities while conveniently fitting into a conventional flat panel interface is what this rotor was made for. A thin, lightweight component with built-in sealing capabilities prevents the introduction of contaminants and allows for an extended lifespan.
