Sensors and actuators
The crank Wheel should be aligned with the sensor
For 36-1 trigger wheels, the minimum diameter recommended is
100mm (4”). Trigger wheels with smaller diameters can be fabricated,
but reading errors may occur and the engine may not work.
Crankshaft trigger sensor
When controlling the ignition with a trigger wheel, it is necessary to
have a sensor that reads the signal from its teeth and informs the
engine position to the injection. There are two types of crankshaft
trigger sensors:
VR sensor: this is the type that is most commonly used in cars
nowadays, especially with 60-2 and 36-1 trigger wheels. One of
its main characteristics is that it does not receive 12V or 5V; it only
generates an electromagnetic signal based on induction. It might have
2 or 3 wires (the third wire is an electromagnetic shield).

Hall Effect sensor: it is usually found on 2, 3 and 4-tooth trigger
wheels and some 36-1 and 60-2 types. It receives a 5V or 12V
feed and emits a square wave signal. It invariably has 3 pins: voltage,
negative and signal.
