Abstract
For manufacturing a housing for sensor elements, a pliable material is introduced into the environment of the sensor element ( ) by an injection molding process. In a first process step, the sensor element is injection-encapsulated by a soft plastic component ( ), and in a second process step a hard plastic component ( ) is applied thereon, which forms the outer housing for the sensor element ( ). The sensor element ( ) is provided with at least two connection leads ( ), which are at least partially encapsulated by the soft plastic component ( ). A sensor manufactured according to the process, especially a temperature sensor, is provided with a measuring resistor as a sensor element ( ) on a substrate with an electrically conducting surface and the resistance layer situated thereon. The measuring resistor is encased by the soft plastic component ( ), which in turn is encapsulated in a hard plastic component serving as a housing.
