As the information source of automobile electronic control system, automobile universal sensor is the key component of automobile electronic control system, and also one of the core contents in the field of automobile electronic technology. There are many kinds of wheel speed sensor, including sensitive wheel rotation, sensitive power transmission shaft rotation, and sensitive differential driven shaft rotation. When the speed is higher than 100km/h, the error of the general measurement method is large, so the non-contact photoelectric speed sensor C03054-22 should be used. The speed range is 0.5-250km /h, the repetition accuracy is 0.1%, and the distance measurement error is better than 0.3%
