Abstract (en)
[origin: WO2019025050A1] The invention relates to a rotational speed sensor (1) for a motor vehicle, particularly a commercial vehicle. The rotational speed sensor (1) comprises: a sensor carrier (4) and a magnetic sensor (5) which is housed in the sensor carrier (4) and which has a defined sensing system for measuring magnetic impulses of a signal wheel provided on the vehicle wheel, a securing flange (2) having a securing device (12) for securing on a vehicle-sided receiving element, electric lines (8a, 8b) for contacting of the magnetic sensor (5), a sensor housing (3) which surroundingly seals the sensor support (4), the magnetic sensor (5) and the electric lines (8a, 8b). According to the invention, in order to provide a compact and safe embodiment, the sensor housing (3) and the securing flange (2) are designed as an injection-moulding body (14), the sensor carrier (4) accommodating the magnetic sensor (5) on the front end area (4a) thereof and comprises a receiving region towards the back, e.g. a wall which is surrounded at least on the outer side thereof by the injection-moulding body (14), preferably also from inside. In order to produce a plurality of different sensors from few initial components in a simple manner, the sensor carrier can be inserted between two first tool halves. Two second tool halves rotatable to the first rotatable halves can determine the mounting flange in a desired angular position with respect to the sensing direction of the magnetic sensor. All components are connected together in a permanent and in a defined position in relation to each by means of the injection-moulding process. With the aid of a stamp which is inserted between the tool halves and on which the sensor carrier is applied, the length of the sensor can be determined.
