Abstract:
An angular position sensor couplable to a device for angular positional sensing of a rotational member thereof, said sensor comprising:a base for mounting to said device;a permanent magnet ring coupled to, and axially aligned with, said rotational member, said magnet ring having an axial bore therein and being diametrically magnetized between a north pole and a south pole thereof;a cylindrical sleeve coupled to said base and disposed circumferentially around said magnet ring such that said sleeve is separated from said magnet ring by an air gap;a pair of diametrically opposed cylindrical segments coupled to said cylindrical sleeve by a circular support member and extending through said bore of said magnet ring, said cylindrical segments having a diametrical slot extending therebetween; anda transducer coupled to at least one of said cylindrical segments within said slot for sensing magnetic force of said permanent magnet ring therein to facilitate said angular positional sensing;a cylindrical flange coupling said permanent magnet ring to said rotational member;wherein said base has a bore therein, and wherein said rotational member extends at least into said bore;wherein a cylindrical sleeve support couples said cylindrical sleeve to said base; andwherein said cylindrical sleeve support is adjustably coupled to said base.
