AND TEC I INNOVAT O L OGY Vishay Sfernice N HN MOTION TRANSDUCERS FOR AERONAUTIC O 19 62-2012 Available Custom Features • Redundant functions with up to 6 resistive elements • Specific mechanical requirements: spring return system, locking position, gears on shaft Resistors - For Aeronautic Applications • Output by flying leads or/and connectors • Integrated switches More than 30 Vishay Sfernice precision potentiometers are used in the Airbus A320 aircraft. In the Airbus A380, the number is closer to 40. Major Airbus Applications • TCU: Throttle Command Unit The fuel command lever instructing on-board computers to increase or decrease the power delivered to the aircraft’s engines • SSTDU: Side Stick Transmitter Damper Unit The cockpit steering mechanism, implemented as joysticks controlled by the pilot and copilot • SBCTU: Speed Brake Control Transmitter Unit A flap used to deploy an air brake that assists the normal braking system to decelerate the plane on landing • BPTU: Brake Pedal Transmitter Unit When the brake pedal is actuated, a Vishay Sfernice potentiometer measures and reports its position • NWSCU: Nose Wheel Steering Control Unit The front wheel positioning instruction given by the pilot or co-pilot (2 levers per plane) during taxiing or parking operations • Temperature Selector Implemented with at least one Vishay Sfernice potentiometer per Airbus, provides temperature control for cockpit, cabin, and cargo areas • Cabin Pressure LFES (Landing Field Elevation Selector) actuated during take-off and landing operations Vishay Sfernice potentiometers are used in many civil and military aerospace programs. Additional Applications • Flight recorders • Servo command positioning • Measuring fluid levels, as in oil tanks • Tail control surfaces • Helicopter flight controls and winch operator automatic hover trim functions • Servo missile fin actuation systems • Servo torpedo rudder positioning Capabilities 2/4 VMN-PL0017-1205 This document is subject to change without notice.
