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

TDK-Micronas HAL 3936-4100 3D-Magnetic Position Sensor is a single-die device in an SOIC8 surface-mount package ideal for modern automotive and industrial applications. This versatile and highly accurate module addresses the industry's demand for robust 3D position sensors, complies with ISO 26262 standards, and includes a low-power mode that facilitates a direct connection to the vehicle's battery for improved efficiency. The integrated SENT interface enables the seamless transmission of external digital signals, enhancing the sensor's versatility in diverse operational environments. TDK-Micronas HAL 3936-4100 3D-Magnetic Position Sensor 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 and is suitable for steering column switches, gear selectors, brake pedal position sensors, and brake stroke sensors.
