Motion sensors used in the IMU (Inertial Measurement Unit) field typically include accelerometers, gyroscopes, magnetometers, and sometimes pressure sensors. An IMU combines readings from these different sensors to achieve 6-dimensional measurements of a vehicle’s motion, orientation, location, and environment. This data can then be used to inform navigation and guidance systems.

S4E5A0A0A111J00 is an application-oriented magnetic angular rate sensor, ideal for automotive applications such as Electronic Stability Programs (ESP), Active Cruise Controls (ACC) and Lane Keeping Assist (LKA).

Working Principles of S4E5A0A0A111J00

The S4E5A0A0A111J00’s angular rate sensing function is based on the anisotropic magnetoresistive (AMR) effect. When a magnetic field is applied to an AMR sensor, its electrical resistance is affected proportionately. The S4E5A0A0A111J00 incorporates three AMR Wheatstone bridge circuits to sense the magnetic field changes along the orthogonal axis X, Y, and Z. Each Wheatstone bridge circuit has one set of positive and negative electrodes that construct two sensor pads. When the device is subject to rate of rotation, the number of electrons on the two sensor pads will be affected differently, resulting in a small voltage difference which can be measured.

The S4E5A0A0A111J00 features adjustable bias functions to fine-tune the zero-rate output and low noise amplifier to minimize the noise interference. A configurable programmable DAC allows users to adjust the output rate sensitivity according to the application requirements. Moreover, temperature compensation and low temperature drift ensure accurate movement measurement in a wide temperature range.

Application Field of S4E5A0A0A111J00

The S4E5A0A0A111J00’s low power consumption and wide temperature range make it ideal for automotive motion sensing applications. The device is highly precise and sensitive, capable of measuring angular rate up to ±200°/s, which is suitable for Electronic Stability Programs (ESP), Active Cruise Control (ACC), Lane Keeping Assist (LKA) and steering angle measurement systems.

The S4E5A0A0A111J00 can also be used in the industrial automation and healthcare fields. In the industrial realm, the device can be used in the development of navigation and guidance systems, robotics, test and measurement equipment, and more. In the healthcare area, the device can be used in the development of injury measurement systems, motion analysis systems, and gait analysis.
