1.4 Mounting (continued)
1.4.2 SMD17K-M12S Mounting
The SMD17K-M12S units are not water tight. Their IP64 rating makes them acceptable for use in dusty envi-
ronments, environments with condensation, and environments where the unit may be exposed to splashing
water. SMD17K-M12S units should be mounted in such a way that condensation and liquids will naturally
drain off of the unit instead of pooling on the motor laminations.
1.4.3 SMD17K-M12P Mounting
The SMD17K-M12P units are water tight. Their IP65/7 rating makes them acceptable for use in washdown
environments and can be exposed to low pressure / low volume water sprays as well as temporary immer-
sions.

1.4.5 Connecting the Load
Care must be exercised when connecting your load to the stepper motor. Even small shaft misalignments can
cause large loading effects on the bearings of the motor and load. The use of a flexible coupler is
strongly rec-
ommended whenever possible.

Maximum radial load is 6.5 lb. (29 N) at the center of the flat on the shaft.

Maximum axial load is 5.6 lb. (25 N)
Internal encoders are mounted on the end of the motor shaft that is internal to the unit. Exces-
sive axial load may cause encoder mis-alignment and damage to the unit. This type of damage
is not covered under warranty.
