TDK-Micronas HAL 39xy Stray-Field Robust 3D Position Sensors feature a range of products that address the requirements for ISO 26262-compliant development. These stray-field robust position sensors measure a 360° angular range and linear movements. The HAL 39xy modules provide setpoint linearization with either 17 variable or 33 equidistant distributed setpoints. The sensors use 3D HAL technology from TDK-Micronas to measure the position of a magnet and suppress external magnetic stray fields by using an array of Hall plates. Only a simple two-pole magnet is needed to measure a rotation angle. Off-axis measurements can also be performed. TDK-Micronas HAL 39xy Stray-Field Robust 3D Position Sensors are available in a SOIC8 package with various interfaces, including SPI, SERIAL, digital, PWM, SENT, and SPC.
