TDK-Micronas HAR 3936-4100 3D-Magnetic Position Sensor

TDK-Micronas HAR 3936-4100 3D-Magnetic Position Sensor is a dual-die device in an SSOP16 surface-mount package designed for modern automotive and industrial applications. This highly accurate and versatile sensor delivers improved redundancy and reliability, and it utilizes a stacked-die architecture, ensuring the synchronous measurements of magnetic signals by occupying the same magnetic field position. As a result, the HAR 3936-4100 provides high-resolution position measurements. This sensor complies with ISO 26262 standards and includes a low-power mode that facilitates a direct connection to the vehicle's battery for enhanced efficiency. TDK-Micronas HAR 3936-4100 3D-Magnetic Position Sensor addresses the industry's demand for robust 3D position sensors and complies with Safety Element out of Context (SEooC) ASIL C standards according to ISO 26262:2018 for compatibility with automotive safety requirements up to ASIL D. The sensor operates in an ambient temperature range of -40°C to +150°C.
