Transducer Mounting
All AMCI resolver based transducers are designed to operate in the industrial environment
and therefore require little attention. However, there are some general guidelines that should be
observed to ensure long life.
hýLimit transducer shaft loading to the following maximums:
Radial Load Axial Load
All 0.625" Shafts 100 lbs. (445 N) 50 lbs. (222 N)
All 0.375" Shafts 30 lbs. (133 N) 15 lbs. (66.7 N)
All Other Shafts 4 lbs. (17.8 N) 2 lbs. (8.9 N)
Table 3.3 Transducer Bearing Loads
hýMinimize shaft misalignment when direct coupling shafts. Even small misalignments
produce large loading effects on front bearings. It is recommended that you use a
flexible coupler whenever possible.
Transducer Outline Drawings
The appropriate outline drawing is included with the transducer when shipped. Outline
drawings for select transducers are also available on the following pages of this manual. If you
are using one of the transducers printed here and need a dimensional drawing, check our web site
or contact us and we will fax you the spec sheet.
