Ignition Hall Effect Sensor: Description and Operation
Hall Effect Distributor
The Hall Effect Pick-Up supplies crankshaft and camshaft position reference signals to the Single Module Engine Controller (SMEC). The Hall effect
device consists of a magnet and a Hall switch mounted with a gap between the switch and magnet. Rotating in the gap is an armature with windows and
tabs. When a tab is in between the switch and magnet, the magnetic lines of flux are shunted through the tab increasing the effect of the magnet on the
Hall switch turning it on. When the window is between the magnet and the Hall switch the magnet alone is not enough to trigger the switch. The digital
output signal of the Hall effect sensor is then used by the SMEC for crankshaft and camshaft position reference signals. The Hall effect pick-up is located
in the distributor assembly.
