Hall sensors minimize stray-field impact
Hall-effect position sensors from TDK-Micronas reduce interference from stray magnetic fields in automotive and industrial applications. The HAL 3930-4100 (single die) and HAR 3930-4100 (dual die) sensors offer robust stray-field compensation and user-configurable PWM or SENT digital output interfaces. Single-die devices are ISO 26262 ASIL C-ready for integration into automotive safety-related systems.
The sensors offer a range of measurement capabilities, including 360° angular measurements, linear movement tracking, and 3D position information of a magnet. A modulo function—primarily for chassis position sensing—allows the partitioning of the 360° measurement range into smaller, more precise segments like 90°, 120°, and 180°.
Both sensors conduct self-tests when starting up and during regular operation to enhance reliability. In addition to chassis position sensing, the devices can be used to detect steering angle, transmission, gear shifter, accelerator, and brake pedal positions.
The HAL 3930-4100 is available in an SOIC8 package, while the HAR 3930-4100 is housed in an SSOP16. For more information on the TDK-Micronas lineup of 3D position sensors, click here.
