Method for manufacture of an inductive sensor

A method for manufacture of an inductive sensor, comprising the steps of:

• placing coils on both sides of a support plate surrounding an opening of the support plate;
• inserting the support plate with the coils into a housing;
• inserting a sleeve through a first cavity of the housing through the opening of the support plate into the housing;
• wherein:
• the sleeve is placed from the outside on the first cavity of the housing, with a collar protruding out over the first cavity;
• welding the sleeve with the housing, wherein the collar of the sleeve is pressed into the first cavity during the welding via application of pressure onto the collar of the sleeve, and during the welding, the collar of the sleeve is brought into the first cavity;
• the end of the sleeve located in the housing is placed in front of a second cavity of the housing, and then is brought into the second cavity during the welding of the sleeve with the housing;
• wherein
• by means of welding, the collar of the sleeve, as well as the end of the sleeve and edge regions of the first and second cavity, become liquid;
• wherein the collar is pressed into the first cavity and the end of the sleeve is pressed into the second cavity;
• and
• the first cavity is welded to the collar, while the second cavity is welded to the end of the sleeve, wherein both weld joints are formed simultaneously in a single working step.
