    • A motion sensor, in particular an rpm sensor for the wheel rotation of a motor vehicle, and a method for producing a motion sensor are proposed, the motion sensor having an integrated circuit (32), connectable via an electrical cable (24), with a measured value transducer and an electronic circuit arrangement for processing the measurement signals. The sensor has a basic component (10), produced by casting or injection molding of thermoplastic, preferably polyamide, by the MID technique, into which basic component a permanent magnet (16) is integrated. A housingless integrated circuit (32) is mounted on the MID component by the flip-chip technique. The arrangement comprising the basic component (10) and the integrated circuit (32) and the permanent magnet (16) as well as the connection end of the cable (24) is sheathed, in a further method step, with an external encapsulation (42) and joined together to form a strong component unit that is well protected against environmental factors.
    • 提出了一种运动传感器,特别是用于机动车辆的车轮旋转的rpm传感器以及用于制造运动传感器的方法,所述运动传感器具有集成电路(32),其可经由电缆(24)与 测量值传感器和用于处理测量信号的电子电路装置。 传感器具有通过MID技术的热塑性塑料(优选聚酰胺)的铸造或注射成型制成的基本部件(10),永久磁铁(16)的基本部件被集成到其中。 通过倒装芯片技术,在MID组件上安装了无住宅集成电路(32)。 包括基本部件(10)和集成电路(32)和永磁体(16)以及电缆(24)的连接端的布置在另外的方法步骤中用外部封装(42 ),并结合在一起,形成一个很好的防止环境因素的组件单元。
