Delphi Digital Speed and Position Sensors - 1

Delphi Digital Speed and Position Sensors 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 offers Digital Speed and Position Sensors with three-wire voltage, or two-wire current square wave output signal interfaces. Most of Delphi's Digital Speed and Position Sensors employ adaptive threshold sensing schemes that improve sensor performance and reduce the sensitivity of the sensor mounting location relative to the target. Delphi's Digital Speed and Position Sensors are available in low (transmission speed), medium (crankshaft position and speed), and high (crankshaft position and speed) switch point accuracy models. The sensors operate with a regulated five volt power supply and/or conditioned 12 volt supply. All can be packaged to meet individual customer requirements. Delphi Digital Speed and Position Sensors shown in two configurations. Modular design based on proven features and assembly processes provides rapid application optimization with flexible package geometry and high reliability Three-wire open collector output, open drain output, or two-wire current output allow flexible controller design Accurate square wave output eliminates square-up function in the controller Transient protection helps protect against stray electro-magnetic fields interface Various mounting applications provide choice of many existing designs, or custom designs Adaptive Hall signal schemes provide improved timing accuracy, optimized sensor air gap and tilt sensitivity, and zero speed sensing capability Single element option offers simplified design, and valid power on state (VPOS) for camshaft applications to minimize engine synchronization timing Dual element differential option offers extremely accurate gear edge detection, peak detector circuitry that is immune to tilt or off-center failure mode, and gain-adjust circuitry that reduces the effect of minor gear anomalies Enhanced sensing capability helps reduce emissions and improve reliability and drivability Typical Applications Delphi Digital Speed and Position Sensors are designed for use with virtually any automotive control module that will accept a digital input. Typical automotive applications include engine (cam and crank: speed and position) and transmission (input and output speed). Because they are designed for demanding applications, Delphi Digital Speed and Position Sensors are also well-suited for a wide range of non-automotive product applications. www.delphi.com | © Delphi.
