There are two types of timing triggers used in various ignition systems. MB uses inductive sensors. These are coils that induce AC voltage as iron is passed near by. These are two wire sensors and actually generate electricity. Hall type sensors have three wires and produce a DC pulse rather than AC. They are powered and generate no electricity of there own.

Miss a signal for a moment and you will miss ignition for that same moment

The only codes are real time duty-cycle codes, no impulse codes.
