ABS Wheel Speed Sensor

The product is designed based on Hall principle, and is installed on the chassis of the car. It is a sensor used to read the wheel speed.

Feature and benefits

Hermetically sealed, magnetically operated non-contact sensing gives excellent life and reliability

Robust construction makes this sensor well suited to harsh environments

High Accuracy

According to customer requirements, a variety of ranges can be customized

The working temperature range is - 40-150 ℃

The temperature resistance of the attached wire of the sensor is - 40-120 ℃

Application

The automobile wheel speed sensor is a subsystem of ABS/ESP, which is used to detect the follow-up signal of wheel speed, convert it into an electrical signal through the Hall effect, and transmit it to the ECU. The ECU judges the speed according to the change characteristics of the electrical signal, so as to regulate the timely work of ABS/ESP

Operate
Basic principle

Hall type wheel speed sensor uses the principle of Hall effect, that is, control current is applied at both ends of the semiconductor sheet, and a magnetic field with a magnetic field strength of B is applied in the vertical direction of the sheet, then an electric potential whose size is proportional to the product of control current and magnetic induction strength B will be generated at the other ends of the sheet, which is called Hall potential.
