Abstract
A sensor unit with at least one magnetic field sensor element, at least one application specific integrated circuit (ASIC) and at least one magnet are arranged in a capsule housing on at least one leadframe. The capsule housing is surrounded by a sensor encapsulation and is intended to have smaller dimensions so as to allow it to be positioned in the encapsulating mold with less effort and at the same time in the exact position. For this purpose, it is provided that the capsule housing has a number of fixing aids adapted in their outer dimensions to an injection mold assigned to the sensor encapsulation.
Claims14
A sensor unit comprising
- at least one magnetic field sensor element,
- at least one application specific integrated circuit and
- at least one magnet on at least one leadframe,
- wherein the at least one magnetic field sensor element, the at least one application specific integrated circuit and the at least one magnet are arranged in a capsule housing surrounded by a sensor encapsulation, and wherein the capsule housing has a number of fixing aids adapted in their outer dimensions to an injection mold assigned to the sensor encapsulation, at least one of the fixing aids retains its original form in the sensor encapsulation and is completely surrounded by the sensor encapsulation, and
- wherein the fixing aids are configured to ensure exact positioning of the sensor element by supporting themselves in the mold of the sensor encapsulation.
