Abstract

An elevator system including an elevator car mounted for movement in the hoistway of a building to serve the floors therein. Permanent magnets in the hoistway and magnetically responsive translating devices on the elevator car coact to provide signals indicative of car position. Two spaced permanent magnets coact with a single translating device, or two spaced translating devices connected in electrical series coact with a signal permanent magnet, to provide a position signal of useful duration at elevated car speeds.
