A trick I've used to see if there are, let's say, vendors for "Hall Sensors"
is to go to Arrow's site: www.arrow.com and do their Line Card search. They
have a huge list of categories that can be further refined into the various
manufacturers/suppliers.

For instance:

"Hall Sensors" gets you: "Allegro"

I've found a bunch of manufactures like Allegro and Temic by this method.
Arrow is also nice enough to have URLs with most of the companies.
