Magnetic Pick Up



Definition:

Magnetic pick-up is a coil, with sensor, and a replacement of mechanical contact breakers, used to produce spark as per the firing order.

Requirement:

It is required in modern electronic ignition system to maintain accurate firing orders in all the cylinders.

Function:

Modern cars are now equipped with a distributor consisting of a magnetic pick-up coil with a sensor mounted on the distributor rotor shaft. The coil, consists of small openings or windows according to the number of cylinders of the engine. When the rotor surrounded by stationary magnets rotates, a magnetic field is generated, which is sensed by the sensor as the coil opening and the magnet face each other. This generates a signal, inside the sensor which is used to trigger the ECU for producing the spark in respective cylinder.

@Desmond Pereira: In an engine, a magnetic pickup is a type of sensor, used to measure the speed of the prime mover. This is very important in case when the output power of the prime mover is supplied to other accessories apart from the Alternator. When the teeth or gears of the engine flywheel move through the magnetic field, a voltage is generated, which is supplied to the ECU to measure the speed of the prime mover.
