The inductive sensor has an electrical coil (14) having winding end portions (114) and current conductors (15) having conductor end portions (115) which are electrically contacted by the winding end portions (114) of the coil in a contact region (18) in the sensor housing (10). A permanently elastic material (26), advantageously silicone, encloses the contact region (18) between the conductor end portions (115) and the winding end portions (114). A temperature-resistant circumferential element (28) bearing on the housing (10) also encloses the contact region (18). This circumferential element (28) can be a polyimide strip or heat-resistant adhesive tape. This inductive sensor allows temperature fluctuation cycles to be increased by up to four times without damaging the coil wire and improves sensor durability.
