Abstract

A sensor including at least one sensor element, at least one signal processing circuit, and at least one housing inside which the sensor element and the signal processing circuit are arranged. The sensor further includes an electronic identification device.

Claims

1. A sensor comprising at least one sensor element, at least one signal processing circuit and at least one package that contains the sensor element and the signal processing circuit, wherein

the sensor has an electronic identification device.

2. The sensor as claimed in claim 1, wherein the identification device comprises at least one data memory unit in which at least one identification datum is storable or stored.

3. The sensor as claimed in claim 1, wherein the sensor has a data transmission interface that comprises a data transmission line or a wireless data transmission unit.

4. The sensor as claimed in claim 3, wherein the data transmission interface is in a form such that it can transmit the at least one identification datum to an external electronic device.

5. The sensor as claimed in claim 3, wherein data transmission interface is in a form such that it can receive the at least one identification datum from an external electronic device and can store it in the data memory unit of the identification device.

6. The sensor as claimed in claim 2, wherein the identification device is in a form such that it comprises and/or stores and/or provides

at least one essentially unique self-identification datum for this sensor as an electronic apparatus and/or

a type identification datum for the sensor, which has at least one piece of information about the specification of the sensor type with which this sensor is associated as an electronic apparatus,

as an identification datum in the at least one data memory unit.

7. The sensor as claimed in claim 1, wherein the signal processing circuit and the electronic identification device and also the at least one sensor element are integrated in at least one electronic component.

8. The sensor as claimed in claim 1, further comprising a leadframe to which the signal processing circuit, the sensor element and the identification device are electrically and mechanically connected, wherein the signal processing circuit, the sensor element and the identification device or the common electronic component and the leadframe are embedded at least to some extent in a plastic package and wherein the leadframe is electrically and mechanically connectable or connected to a connector or a cable.

9. The sensor as claimed in claim 8, wherein the sensor has a single plastic package.

10. The sensor as claimed in claim 1, wherein the sensor is in the form of a wheel speed sensor.

11. The sensor as claimed in claim 2, wherein the sensor has a data transmission interface that comprises a data transmission line or a wireless data transmission unit.

12. The sensor as claimed in claim 4, wherein data transmission interface is in a form such that it can receive the at least one identification datum from an external electronic device and can store it in the data memory unit of the identification device.

13. The sensor as claimed in claim 7, wherein the at least one electronic component is in the form of an ASIC.

14. The sensor as claimed in claim 8, wherein the signal processing circuit, the sensor element and the identification device are integrated in a single common electronic component.
