ABSTRACT:
A magnetic sensor for a distributorless ignition system is useable in an internal combustion engine. A Hall-effect device is spaced intermediate a pair of opposing permanent magnets for concurrently generating dual magnetic flux fields within respective air gap regions formed between each of the magnets and the device. Alternatively a magnet is placed between two Hall-effect devices to define the regions. A toothed disk rotatably connected to the crankshaft of the engine causes different teeth to shunt the fields in each of the regions in a predetermined sequence for generating pulses at the device output indicative of the firing order of the engine. Alternatively, a disk having outer and inner notched rims is used to shunt the fields in each of the regions. Further, an elongated channel shaped member has sides movable in the regions for detecting relative linear motion between two parts.
