ABSTRACT:
This disclosure relates to a directional sensing arrangement including a rotatable member having a plurality of permanent magnets which magnetically influence a first and second spaced stationary sensor. The rotation of the member causes the magnets to sequentially operate the first and second sensors so that neither, either or both are actuated. The first and second sensors are coupled to a logic network which deciphers the sequential actuations for determining the direction of rotation of the rotatable member.
