Hall-effect magnetic torque sensor boosts EPS for sustainable vehicles

The SX-4462 Hall-effect magnetic non-contact torque sensor is a flexible and cost-effective sensor announced by TT Electronics.

The fourth-generation Magnetorque lightweight steering sensor is accurate and reliable, with 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) is accompanied by TT’s system expertise and development support. Customisation options include full-scale range and sensitivity, wire length, product marking and connector type. The 4.5 to 5.5V supply voltage range simplifies connection to a convenient power source, and the maximum current of just 20mA ensures always-low power consumption. Redundant outputs that allow full diagnostics and output voltage clamps that enable open/short detection ensure performance under harsh conditions, assures TT.

TT’s MT4 Magnetorque family of torque sensors allows secure, tactile steering control, unaffected by vibration, contamination or wear factors that impair ordinary contacting sensors. In addition to ORVs, including all-terrain vehicles (ATVs) and utility terrain vehicles (UTVs), it can be used in industrial vehicles used in locations such as quarries, factories, farms, or construction sites.

The lightweight sensor weighs just 82g and is engineered for high linearity near the zero-degree position, and torque angle of ±5 degrees. It performs multi-turn measurement over ±2.5 turns with typical sensitivity of up to 0.4V/degree.
