MAGNETIC GUIDE

摘要

A magnetic guide provides a ferrous metal follower (38) and a leader magnet (40). The magnetic flux associated with the leader magnet (40) permeates the ferrous metal follower (38) and establishes a magnetic coupling between the ferrous metal follower (38) and the lead magneti (40) so that the ferrous metal follower (38) moves in response to the movement of the leader magnet (40). A shielded magnetic reed switch (16) positioned adjacent to the ferrous metal follower (38) actuates a predetermined distance at which magnetic coupling is formed.
