magnetic proximity sensor / cylindrical
0.127 mm, 6.35 mm
Magnetic sensors developed by Monarch Instruments come in two models: M-190, MT-190. The M-190 has a rotation frequency of 1-99,999 RPM and a self-powered gear sensor. It has two submodels: the M-190W and the M-190W. These two have magnetic sensors which are usually used with 60 tooth 20 pitch gears. They mount with 0.005 inches (0.127mm) of a 0.1 inch (2.5mm) target.
Like the M-190, the MT-190 also has two submodels, which are the MT-190W and the MT-190P. Both have a rotation frequency of 1-99,999 RPM. They differ from the M-190 models through the enhanced performance of their amplifiers which extend the operating gap to 0.25" from the target.
