Abstract

Magnetic sensor device (100) for sensing an external magnetic field (60), the magnetic sensor device (100) comprising a plurality of branches (110-140) electrically connected in a bridge circuit. At least one branch comprises a magnetic sensitive branch configured to sense the external magnetic field. Each branch (110-140) comprises a plurality of sub-branches (111-141) electrically connected with each other. The sub-branches (111-141) in each branch (110-140) are arranged within a sensing area (160). The sub-branches (111-141) in a branch (110-140) have a centroid (C160) that is common to the centroid of the sub-branches (111-141) in another branches (110-140). The magnetic sensor device provides a read signal that is less sensitive to inhomogeneities in the external magnetic field. Also disclosed is a magnetic sensor system comprising at least one magnetic sensor device.
