Tachogenerators and magnetic variable reluctance (VR) probes are two examples of speed sensor types. A tachogenerator is a shaft-driven electrical generator with a speed-related variable frequency output.
Although they are quite robust, these devices have a weak output signal. Magnetic fields can be detected as flux, strength, and directions using magnetic sensors. Measurement and detection of magnetic fields have long been crucial operations in numerous applications.
The global magnetic speed sensor ICs market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Honeywell Speed Sensor ICs. A ring magnet encoder target’s position, direction, and speed are all detected by the VM Series. VF401 detects ring magnets with a precise pitch.
The VF526DT outputs both direction and speed. VG481V1 measures a ferrous gear target wheel’s speed. The VM Series Anisotropic Magneto resistive (AMR) Integrated Circuit (IC) product line uses an original (patent-pending) bridge design and configuration to detect the speed and direction of a ring magnet encoder target.
The three products comprise 2- and 4-pin AMR sensors for shaft speed measurement in pumps, motors, and compressors as well as for speed, speed and position sensing in transmissions, engine cranks, wheel speed measurement, integrated bearings, and sealing.
Highest accuracy speed measurement is provided by Infineon XENSIV magnetic speed sensors ICs for use in safety and powertrain applications.
For the purpose of safety and powertrain applications, magnetic speed sensors are crucial parts. Anywhere the rotational speed of a shaft needs to be detected, Infineon XENSIV magnetic speed sensors are employed. These speed sensors use contactless magnetic sensing to measure various speeds and transmit the results as an appropriate output signal.
Magnetic speed sensors from Infineon use Hall-effect and GMR-based technologies to calculate linear and rotational speed. A magneto resistive GMR speed sensor derives its measurement from the alteration in sensing element resistance brought on by the varying magnetic field application.
The Hall effect, which describes the generation of a voltage when a charge is applied, is used by a Hall-effect speed sensor. To measure speed and location, ferromagnetic gear tooth wheels or encoders can be utilized with Infineon magnetic speed sensors. Additionally, magnetic speed sensor ICs offer advantages such built-in capacitors for the greatest levels of electrostatic discharge (ESD) protection and high electromagnetic (EMC) resilience.
Infineon speed sensors are useful technologies in industrial settings in addition to a variety of automotive applications, monitoring speed, achieving CO2 targets, and creating intelligent, secure powertrain solutions.
