- the senor comprises a lead frame, with said signal processing circuit, the sensor element and the identifying means are electrically and mechanically connected, in particular that the Signalverarbei ⁇ processing circuit, the sensor element and the identifying means are integrated in a single common electronic component, wherein the signal processing ⁇ circuit, the sensor element and the identification device or the common electronic component and the Leadframe are at least partially embedded in a plastic housing ⁇ and wherein the leadframe with a plug or a cable is electrically and mechanically connected or connected.
- the sensor preferably has a single plastic housing.
- the senor is formed as a wheel speed sensor ⁇ .
- the invention also relates to the use of the sensor in motor vehicles.
- the invention also relates to a manufacturing method or to a programming method in
- Frame of a manufacturing method of the sensor in particular by means of an external electronic device, in particular comprising a database, wherein the external electronic device is expediently connected to the interface signal processing unit of the sensor, particularly preferably by means of a cable.
- Fig. 1 shows an embodiment of a sensor.
- FIG. 1 illustrates an exemplary sensor having leadframe 7 with mounting island 9, on which a common electronic component 6, designed as an ASIC, is arranged.
- the ASIC 6 comprises a sensor element 1, by way of example an AMR sensor element, a signal processing circuit ⁇ 2, an identification device 4 and a data transmitting interface 5, jointly integrated on the chip of the ASIC on.
- ASIC 6 is connected to the leadframe 7 by means of Bond wires electrically connected.
- ASIC 6, the mounting island 9 of the leadframe 7 and a part of the leadframe are injected and packaged in a single plastic housing 3.
- Identification device 4 has, for example, a data storage unit, not shown, in which at least one identification data item can be stored or stored or overwritten.
