Hall effect sensors happy to partly run in hot engine oil?
Posted: Thu Feb 11, 2016 10:50 pmI will need a Hall effect cam position sensor that will run, pick up side, in a hot engine oil environment and has provision to seal into or against a flat plate. I have used Bosch 0 232 103 022 sensors in the past, but these have been in fresh air. I am not sure whether they would like or even tolerate a hot, wet oily environment. I work on lots of 2JZ-GTE Supra twin turbo engines and these have 2 cam position sensors that pick up off pegs cast into the intake cam, and run bathed in hot oil on the engine side, within the cam box of the head. I think they are magnetic, not Hall effect though, and are rather big. They are also very expensive, new.
Has anyone any ideas for a Hall sensor that is happy with half of itself in hot oil, can be sealed to a flat surface, and is reasonably priced and easily sourced? Ford TDCi ones seem to look as if they are designed to run in oil, and are cheap. Are they Hall effect though? Connector plug and pin availability is also a thought! Thanks.
