Delphi Digital Speed and Position Sensors are based on integrated adaptive threshold Hall effect technology. They sense the speed and position of a target created with various sense features that are machined, stamped, drawn, or magnetically encoded. They can sense speeds as low as zero RPM. Delphi Speed and Position Sensors feature silicon Hall sense elements. The sensor assembly uses proven design features and assembly processes to provide a reliable solution in demanding automotive environments. The sensor design is modular to enable re-use of proven components and to provide low risk package modifications for new applications. They utilize an adaptive threshold control scheme providing robust performance that improves the air gap capability and reduces the placement accuracy requirements between the sensor and the target. Delphi also offers designs that help protect the sensor from transients and from electromagnetic interference (EMI). Power can be provided by either battery or regulated voltage supplies, enabling even more controller flexibility. Delphi's Digital Speed and Position Sensors can operate on conditioned voltage from 4.5 to 16 volts.
