A speed sensor
By using two chips and a power connector in the speed sensor, the problem of limited space in the vehicle body that prevents the installation of two sensors is solved. This enables the simultaneous measurement of the rotational speed of two target shafts in a limited space, reducing costs and simplifying electrical connections.

AI Technical Summary
Technical Problem
The problem of not being able to install two speed sensors when there is limited space in the vehicle body or when the two target axes are in close proximity.
Method used
Design a speed sensor that uses two chips and a power connector. By rationally arranging the circuit, two independent signals are output using three pins, reducing the number of sensors and mounting holes.
Benefits of technology
It enables simultaneous measurement of the rotational speeds of two target axes within a limited space, reducing costs, avoiding magnetic field interference, simplifying electrical connections, and saving space.
