Dual Hall Effect sensors can detect both rotation and speed simultaneously. In order to enable the Quadrature signal to calculate rotation, the sensor outputs a frequency signal on channel A and a 90° phase-shifted frequency signal on channel B.
The Global Two-Wire Hall-Effect sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Melexis MLX92241 is based on the company’s most recent mixed signal submicron CMOS platform for Hall-effect devices. In a single package, the device combines a voltage regulator, a Hall sensor with an advanced offset cancelling mechanism, an output driver configured as a current sink, and an integrated capacitor.
The magnetic core is adopting an upgraded offset cancellation technology based on the tried-and-true platform, enabling faster and more precise processing while being temperature insensitive and stress independent. Additionally, a pre-programmable temperature coefficient is used to make up for some magnet types’ natural tendency to lose strength as temperature increases.
The inbuilt voltage regulator works between 2.7 to 24V, thus it can be used in a variety of applications. Even remote sensors can be configured for low voltage operation down to 2.7V while being reverse voltage resistant since the built-in reverse voltage protection eliminates the need for a serial resistor or diode on the supply line.
Under-voltage lock-out protection will immediately freeze the device in the event that the supply voltage drops below the minimal level while it is in use, shielding the magnetic measuring circuitry from the effects of any electrical disturbance. Therefore, only correct magnetic measurement results are used to update the output current state. In addition to saving one wire, the two-wire interface enables the inclusion of diagnostic features like reverse polarity connection and fault detection.
