hall sensor?not what is it

[bruce plecan]

ref Duane Reed:
  If you can use the GM sensors then they have the magnet
as part of the sensor, and all ya need to do is fab an interuptor
ring..  All the 85-87, buick turbos used this type, and there are
lots of others, but jus wanted to point ya inna direction.
  Might look around like the speed sensor off a 700R4 just
relies on a reluctor on the output shaft.  Then Chyrsler uses
some in there distributors.
