Electronics
has unveiled the SX-4462, a Hall-effect magnetic
non-contact torque sensor offering flexibility, high accuracy, and diagnostic
capabilities for electronic power steering applications. Designed for off-road
vehicles, three wheelers, light commercial trucks, and tractors, the new sensor
provides redundant outputs that allow for full diagnostics and output voltage
clamps that facilitate open/short detection for high performance in harsh use
conditions.

The
MT4 Magnetorque family of sensors provide secure tactile steering control that
performs even under vibration, contamination, and wear conditions. These devices
are suited for ORVs, including all-terrain vehicles (ATVs)
and utility terrain vehicles (UTVs), as well as industrial vehicles used in
locations such as quarries, factories, farms, or construction sites.

The
fourth-generation Magnetorque is customizable, offering a range of options
including full-scale range and sensitivity, wire length, product marking, and
connector type. Key specs include a 4.5-V to 5.5-V supply voltage range, which
simplifies connection to a convenient power source, and a maximum current of 20
mA, which ensures low power consumption.

The
sensors weigh only 82 grams and is engineered for high linearity near the
zero-degree position and a torque angle of ±5°. It is capable of multi-turn
measurement over ±2.5 turns with typical sensitivity of up to 0.4 V/°.
