Circuits for magnetic pickups

or the phillips sensor for this application, but I cann't remember 
it's code just not - $30NZ per ($20US) with all the circuitry on 
board, etc, uses magneto-resistance, and a magnet - can even give you 
direction in the flasher model (sooo useful on crank.., meant for 
ABS, I suspect..) - 2 wire 12 volt connection, current mode data, 
etc. very nice.

but then Tony knows about that one... just thought others may wish to 
know.. If anyone asks, I will dig up the data..
