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

The Camshaft Position Sensor plays a vital role in your engine’s operation; to determine the exact position and speed of the camshaft(s) to the ECM. The ECM uses this information to determine fuel and spark timing as well as VVT operation. A failed sensor can result in a check engine light, hard starting or failure to start, increased vehicle emissions and engine misfire. NTK Camshaft 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 camshaft
• 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

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

Product Features:

• OE QUALITY: Designed to meet or exceed OE specifications, fit, form and function ensures proper position, rotating speed of the camshaft or 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

Made In USA. Melling engine assembly lube, MELL-LUBE, is formulated to be an initial lubricant on camshaft metal surfaces as well as related valve train parts. The added zinc material (1400 ppm) provides MELL-LUBE with added protection to prevent scoring and galling during initial engine start-up for both newly rebuilt and / or remanufactured engines. In addition, MELL-LUBE contains corrosion inhibitors to prevent rust and pitting of components. MELL-LUBE mixes with any engine oil and will not clog filters. Melling recommends MELL-LUBE be a part of every camshaft install.
