The Crankshaft Position Sensor plays a vital role in your engine’s operation; to determine the exact position of then engine’s crankshaft to the ECM. The ECM then uses this information to determine fuel and spark timing or engine misfire detection. A failed sensor can result in a check engine light, failure to start, intermittent stalling, or misfire. NTK Crankshaft Position Sensors are a premium quality product with outstanding support and leading innovation bred from our OE heritage.

Product Features:

• THE NTK DIFFERENCE: Enhanced, robust circuit board traces and precision-wound coated-copper windings increase durability, longevity and performance
• OE QUALITY: Designed to meet or exceed OE specifications, fit, form and function to ensure proper position and/or rotating speed of the crankshaft
• EXTENSIVE TESTING: 100 percent thermal shock and vibration tested for best in class performance and reliability in the most extreme conditions
• PRODUCT ENGINEERING: Premium seals prevent leaks or corrosion, while optimized magnet size and strength ensures precise, consistent signal output

Designed digital output for maximum signal to noise ratio. Not impacted by temperature changes and provide robust, long-lasting sensor protection. Manufactured to meet or exceed OE requirements.

Product Features:

• The sensors provide accurate readings from the gap between sensor contact and element due to its design
• Manufactured to meet or exceed OE requirements
• Enhanced sensing functionality helps reduce emissions, improve reliability and drivability
• Not impacted by temperature changes and provide robust, long-lasting sensor protection
• Designed digital output for maximum signal to noise ratio

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.

Product Features:

• 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
