Abstract:
A method for matching a sensor with respect to a predetermined location of a target wheel comprising the steps of:providing a sensor that produces an input signal and a reference signal, wherein the input signal is responsive to predetermined variations of an adjacent rotating article;providing the target wheel having a predetermined pattern of variations to which the input signal is responsive, wherein the target wheel is identical to a predetermined target wheel that the sensor will be operatively paired with subsequently;placing the sensor facing a preselected segment of the target wheel at a predetermined distance from, and at a predetermined orientation with respect to, a selected surface the target wheel;connecting the sensor to an electrical circuit wherein a binary output signal is provided responsive to comparison between the input and reference signals, and wherein a first output signal of the binary output signal is produced; andadjusting one of the input and reference signals with laser trimming a selected resistor so as to cause the binary output signal to switch to a second output signal.
