Abstract
Magnetic field sensor arrangement for positioning in a gap formed between end faces (12) of a magnetic core (4), comprising a magnetic field detector (5), a housing (10), and a grounding device (8), the magnetic field sensor and grounding device being mounted to the housing. The grounding device comprises at least one contact (20) elastically supported and configured for electrical contact with the magnetic core. The elastically supported contact is mounted adjacent a sensing portion of the magnetic field sensor and configured for insertion in the magnetic circuit core gap such that the contact elastically biases against the end face of the magnetic core.
Claims23
A magnetic field sensor arrangement comprising:
- a magnetic field detector for positioning in a gap formed between end faces of a magnetic circuit core;
- a housing;
- a grounding device;
- and
- a circuit board on which the magnetic field detector, the housing and the ground device are mounted;
- wherein the magnetic field detector and the grounding device are mounted to the housing,
- wherein the grounding device comprises at least one contact elastically supported and configured for electrical contact with the magnetic circuit core,
- wherein the elastically supported contact is mounted adjacent a sensing portion of the magnetic field detector and configured for insertion in the magnetic circuit core gap such that the contact elastically biases against said end face of the magnetic circuit core,
