Fullerton, Calif. TT electronics BI Technologies Electronic Components Division has developed a non-contacting torque sensor, based on its Magnetorque technology, for electric power steering systems. The steering sensor features dual-phased outputs for reliable diagnostic characteristics.
The Magnetorque sensor has an accuracy of ±3% (±1.5% available) and hysteresis of 1%, with a rotational life of 25 million revolutions. The operating voltage is 5.0 V (±10%), with a maximum current consumption of 10 mA per output. The operating temperature range is -40°C to +125°C.
Magnetorque sensors are programmable for gain and offset. At the time of assembly, customers can program the gain and offset values, allowing for adjustments to the mechanical tolerances in their system.
The Magnetorque sensor can be integrated into a single package with BI's digital angular position sensor (DAPS) technology. This provides a torque and position signal in one package. Integrated connector and lead wire options are also available.
Pricing: Approximately $16 each in quantities of 100,000 depending on features and packaging options.
