Magnetic Sensors are solid-state electronic detection components designed to sense and measure changes in magnetic fields, translating physical position, rotation, speed, or electrical currents into readable analog or digital signals. Operating as non-contact sensing elements, magnetic sensors eliminate mechanical wear, oxidation, and contamination failures, making them highly reliable in automotive steering, industrial robotics, and consumer lid closures.
This broad category includes Hall-effect switches, linear Hall sensors, anisotropic magnetoresistive (AMR), giant magnetoresistive (GMR), and tunnel magnetoresistive (TMR) sensors. Critical engineering metrics focus on magnetic sensitivity (Gauss or milli-Tesla), operating thresholds, supply voltage, frequency bandwidth, operating temperature range, and output interfaces (analog, PWM, I2C, SPI).
