CONTROLS WCS-134143Rev c - April 8,2008Non-contact Rotary Position Sensor Features • Dual Ratiometric APS output • Independent, Isolated APS circuits • IP66 Sealed • Highly EMI resistant (SAE J1113) • +5V Operation • Integral Preload Spring • Integral Metripack 150 Series Connector • Protected against Electrical Misconnection Applications • Truck Throttle Position Sensor Description: This device is a solid-state rotary position sensor that provides a dual linear output voltage proportional to absolute shaft rotation in either direction from a reference angle. It operates from +5V power typically supplied by a vehicle engine control unit (ECU). This device’s two outputs are independent and electrically isolated, supporting the implementation of highly fault tolerant and reliable systems.
