MS Series Magnetic Pickup mounted near the observed gear outputs a frequency
signal (detected frequency) proportional to the rotating speed of rotating machinery.
Specifications

Gear material
It should be a high permeability magnetic material(SS400 is
recommended).
Gear shape
Involute gears are most suitable. Gears with large modules or different
shapes may cause large waveform distortion that prevents accurate
detection. If the rotating shaft moves in the axial direction, take care that
the pole center is not dislocated from the gear.
