Hall effect sensor boosts EPS drivability for safer and sustainable motoring

03-12-2018 | TT Electronics | Test & Measurement

TT Electronics has released the SX-4462 Hall effect magnetic non-contact torque sensor, a flexible and cost-effective sensor providing high accuracy and diagnostic capabilities for EPS applications comprising ORVs, three-wheelers, light commercial trucks, and tractors.

The SX-4462 fourth-generation Magnetorque (MT4) is simple to integrate, leveraging the company's system expertise and development support. Added flexibility is provided by customisation options incorporating full-scale range and sensitivity, wire length, product marking and connector type. The 4.5V-5.5V supply voltage range simplifies connection to a convenient power source, and the maximum current of just 20mA assures always-low power consumption. Redundant outputs that enable full diagnostics and output voltage clamps that enable open/short detection ensure flawless performance under the toughest use conditions.

The company's family of torque sensors enables secure, unaffected by vibration, tactile steering control, contamination or wear factors that impair ordinary contacting sensors. It is ideal for ORVs, including ATVs and UTVs, as well as industrial vehicles used in locations such as quarries, factories, farms, or construction sites.

Weighing just 82g, this lightweight sensor aids vehicle economy and dynamics. 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/degrees.
