Position sensors are a type of technology used to measure any position or displacement. They are used to detect movement and also to keep track of the precise location of a physical object or device. The AS5162-HSOM is a high-resolution, configurable Hall-effect Angular Position Sensor. It is designed to provide high accuracy and flexibility in a wide variety of applications. This article will discuss the application fields and working principles of the AS5162-HSOM.

Application Fields

The AS5162-HSOM is used mainly in the automotive industry for applications such as throttle pedals, accelerator pedals, Cruise Control, airbag system deployment timing, transmission shifters and steering wheel angle measurements. It is also a popular choice for use in suspension systems, power windows, and consumer electronics such as electric guitars, treadmills, and elevators.

The AS5162-HSOM is designed to provide the highest possible resolution and accuracy for both linear and angular measurements. It utilizes a high-resolution Hall element that is placed between two magnets and a custom ASIC. The ASIC contains the necessary logic and control to convert the measurement signal into a digital output. This digital output is then sent to the microcontroller or other system controller, where it can be used for a variety of applications.

Working Principle

The AS5162-HSOM works based on a magneto-resistive sensing principle. This sensing principle uses the Hall effect to measure magnetic fields. When a magnet is placed in close proximity to a Hall device, a voltage is generated with a magnitude and direction proportional to the strength of the magnetic field. By placing two magnets surrounding the Hall element, a different voltage will be generated dependent on the magnetic field’s orientation, thus making it possible to measure angular position.

The AS5162-HSOM utilizes a sophisticated ASIC designed specifically to convert the read signals into a digital output that can be used in a microcontroller or other system controller. The ASIC includes several features such as a CMOS sensor, a 12-bit sigma-delta ADC, a selectable Hall amplifier, and programmable temperature compensation. The ASIC also contains bias circuits which can be used to adjust the sensitivity of the sensor and to minimize electrical interference.

The AS5162-HSOM is also designed with a wide range of features optimized for the automotive environment. The wide temperature range of -40°C to 150°C, EMC tested signals, and high-speed communication protocols make the AS5162-HSOM the perfect choice for applications in the automotive industry.

Conclusion

The AS5162-HSOM is a high-resolution, configurable Hall-effect Angular Position Sensor designed for applications in the automotive industry. It utilizes a sophisticated ASIC containing the necessary logic and control to convert the measurements into a digital output. It is designed with several features optimized for the automotive environment such as a wide temperature range, EMC tested signals, and high-speed communication protocols. The AS5162-HSOM is a popular choice for use in suspension systems, power windows, and consumer electronics.
