Mounting Considerations
The HEDS-5540 and 5640 three channel encoders and the
HEDM Series high resolution encoders must be aligned
using the aligning pins as specified in Figure 3, or using
the HEDS-8910 Alignment Tool as shown in Encoder
Mounting and Assembly.
The use of aligning pins or alignment tool is recommend-
ed but not required to mount the HEDS-5500 and 5600.
If these two channel encoders are attached to a motor
with the screw sizes and mounting tolerances specified
in the mechanical characteristics section without any

additional mounting bosses, the encoder output errors
will be within the maximums specified in the encoding
characteristics section. The HEDS-5500 and 5540 can be
mounted to a motor using either the two screw or three
screw mounting option as shown in Figure 2. The optional
aligning pins shown in Figure 3 can be used with either
mounting option. The HEDS-5600, 5640, and HEDM-5600
have external mounting ears which may be used for
mounting to larger motor base plates. Figure 4 shows the
necessary mounting holes with optional aligning pins and
