Connectors, wheel speed sensors

Wheel-Speed Sensor Installation, Cable Layout, and Connector... 

Wheel-speed sensors are available with or without (direct connected sensors) cable. Cable routing in the car is important and many types of sensor configuration (cable layout) are possible. Grommets and clips can fix the cable to the car body. Expansion bellows of plastic protect the cable from damage. Fig. 7.9.12 shows a complete WSS consisting of sensor head, connector, grommets, clips, and expansion bellows. The fixture to the car body with clips and grommets is shown in Fig. 7.9.13. 

Joining the wheel-speed sensor to the cable tree is done with a connector. The demands on the connector are low contact-resistance, safe connection by connector pins under the influence of dynamic impact, and pin material resistant to corrosion. Depending on the installation area, the further requirement of tightness may be necessary. Fig. 7.9.14 shows three examples of connectors.
