Hall-Effect Torque Sensor Boosts EPS Drivability

TT Electronics’ SX-4462 Hall effect magnetic non-contact torque sensor embarks as a flexible and cost-effective sensor offering high accuracy and diagnostic capabilities for electronic power steering (EPS) applications including off-road vehicles (ORVs), three-wheelers, light commercial trucks, and tractors.


The SX-4462 fourth-generation Magnetorque (MT4) offers customization options including full-scale range and sensitivity, wire length, product marking, and connector type. A 4.5V to 5.5V supply voltage range simplifies connection to a convenient power source, and a maximum current of 20 mA ensures low power consumption. Redundant outputs that allow full diagnostics and output voltage clamps that enable open/short detection ensure reliable performance under tough conditions.
