Notes:
1. These are tolerances required of the user.
2. The AEDM-5805, 5905 provide an 8.9 mm (0.35 inch) diameter hole through the housing for longer motor shafts. See Ordering Information.
3. The recommended mounting screw torque for 2 screw and external ear mounting is 1.0 kg-cm (0.88 in-lbs). The recommended mounting screw
torque for 3 screw mounting is 0.50 kg-cm (0.43 in-lbs).
