摘要
The multi-turn absolute encoder (1) for detecting the absolute position of a rotatable element in plural turns comprises a magnet (2) connected to the element in order to rotate therewith ; an absolute detection device (3) for detecting the absolute position of the element in a single turn; and a multi-turn detection group (4) for determining the number of turns performed by the element, which comprises at least three actuatable switches (4A, 4B, 4C) positioned around the magnet (2) in order to be capable of distinguishing at least three different positions of the element in a single turn.
