Mounting with Aligning Pins
The HEDS-9040 and HEDS-9140 can also be mounted
using aligning pins on the motor base. (Avago does not
provide aligning pins.) For this conguration, Side A
must be used as the mounting plane. The aligning recess
centers must be located within the 0.005 in. Radius Tol-
erance Circle as explained in “Mounting Considerations.”
