Re: Gear tooth sensors - Forward or backward?

You are correct. Last year's gear tooth sensor (ATS651LSH) had two different pulse widths depending upon direction of rotation ( 45 us and 90 us - typical ). For this year's gear tooth sensor (ATS642LSH) the pulse width will vary based upon the speed of the rotation of the gear and the shape of the gear teeth as seen by the sensor. see the complete data sheet at www.allegromicro.com
