An electronic device called a Hall effect sensor is made to detect the Hall effect and turn the results into data that can be used to switch a circuit on and off, measure a changing magnetic field, be processed by an integrated computer, or be shown on an interface.
The existence (or absence) of a magnetic field is detected using Hall effect switches, also known as unipolar sensors, in comparison to a predetermined threshold for magnetic flux.
The switch opens (shuts) when an adequate magnetic field is detected, and closes (opens) when the field is no longer there (opens)
The Global Magnetic Hall Effect Sensors 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.
SII Introduces New High-Accuracy Hall Effect Sensor ICs for Automotive Use—High Performance/High Accuracy with Magnetic Operating Point Accuracy +/-1.5mT, Developed Specifically for Reliable Position/Rotation Detection in Demanding Automotive Applications.
Depending on the polarity and strength of the magnetic field, Hall Effect sensor ICs can output high or low voltage levels when detecting magnetic field changes.
Designers can construct applications that function based on detecting open/close situations, relative position, rotation, and direction by coupling the sensors with magnets.
Unipolar (S-57A1), used to detect open/close conditions like doors, seat belts, CD/DVD players, and shift levers, and Bipolar (S-57K1), used to detect/measure rotation and direction like EPS motors, power windows, and windshield wipers, are the two basic types of sensors in the SII Hall Effect sensor series.
The S-57A1/K1 series has a wide working voltage range (VDD = 3.5 to 26.0 V), a temperature operating range (-40C to 125C), and high-speed operation (tCYCLE = 16 microseconds (S-57A1) and 8 microseconds (S-57A1) in addition to high performance and high precision (S-57K1).
The sensor IC’s compact SOT-23-3 (2.92.81.3mm) and lead (Pb) and halogen-free packaging make integration in an automobile setting incredibly efficient and green. In order to help clients with system design, including magnet selection and relative dimensions/locations, SII also offers a magnetic simulation consultancy service.
