Industry welcomes NTK camshaft & crankshaft sensors

NGK’s range of premium NTK camshaft and crankshaft sensors (also known as engine speed & position sensors) have proved to be a popular addition to the company’s portfolio since being launched last year.

The range – comprising more than 200 UK-specific part numbers with excellent UK vehicle parc coverage – opened up further sensor replacement opportunities for aftermarket customers.

Cam and crankshaft sensors are a vital part of the engine management system and provide information about engine speed and the exact position of several engine parts, camshaft/valves, and crankshaft/pistons. Supplying this information to the engine control unit (ECU) enables the fuel injection and ignition systems to function efficiently.

Mark Hallam, Marketing Manager, NGK Spark Plugs (UK) Ltd, said: “NGK has always been renowned as a supplier of original equipment spark plugs, glow plugs and NTK Lambda sensors to the world’s leading vehicle manufacturers and the independent automotive aftermarket and in recent years has also become increasingly well known for its expanding NTK sensors’ range.

“Our NTK camshaft and crankshaft sensors have been very positively received by our UK and Ireland customers since being launched in April last year. NTK has more than 40 years’ experience in the sensor business and the comprehensive range of premium camshaft and crankshaft sensors further confirmed our position as the UK’s leading ignition and sensor supplier, proving extremely popular with our distributors and their garage customers.”

Crankshaft and camshaft sensors provide information about engine speed and the exact position of crankshaft/pistons and camshaft/valves. Because ‘timing is everything’, supplying this information to the engine control unit (ECU) enables the fuel injection and ignition systems to function efficiently.

The sensors use either Hall effect or inductive principle and are not interchangeable. Some are designed to operate ‘dry’, some in oil contact.

Hall effect sensors have integrated electronics, an external 5V power supply and a square output signal (0V/5V). They can detect a ‘position’ even when the trigger wheel is stationary. Compared to inductive type, they have less sensitivity to electromagnetic interference and changes in the air gap between sensor and the trigger have no direct effect on the signal. They have three pin connectors.

Inductive sensors generate a signal, have no external power supply, and have a wave-form output signal. A signal is generated only as the ‘trigger wheel’ passes by. Voltage rises as the trigger wheel increases speed. The mounting distance between the sensor and trigger wheel is important. They have two or three pin connectors, the third being a shielding ground connection.

Whichever design principle, the sensor delivers the input signal for the ECU. Without that signal the engine runs poorly, hard starting results or vehicle breakdown occurs.
