Abstract
A magnetic field sensor has a carrier element (1) made from metal, on which a holder (2) with a sensor element (3) is fixed in a set position. For this, the holder (2) engages with holding tongues (9, 10), having barbs (11), in recesses (12, 13) in the holder (2). An interspace (15), filled up by an extrusion coating (16), which also surrounds the remaining holder (2) hermetically, exists between the holder (2) and the carrier element (1) through the bearing of the holder (2) against a stop surface (14) of the holding tongue (9, 10).
Claims7
A magnetic field sensor having a carrier element made of metal, on which a holder with a sensor element is fixed in a set position and joined to the carrier element in a sealing manner by extrusion coating, wherein the carrier element (1) engages with at least one holding tongue (9) in a recess (12, 13) in the holder (2), the tongue 9 having barbs (11), and an interspace (15), filled up by the extrusion coating (16), is formed between the holder (2) and the carrier element (1) by bearing of the holding tongue (9,10) against a stop surface (14) of the recess (12,13).
