Mechanical Characteristics
Notes:
1. These are tolerances required of the user.
2. The HEDS-55X5 and 56X5, HEDM-5505, 5605 provide an 8.9 mm (0.35 inch) diameter hole through the housing for longer motor shafts. See
3. The HEDS-5540 and 5640 must be aligned using the aligning pins as specified in Figure 3, or using the alignment tool as shown in “Encoder
4. 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
Electrical Interface
To insure reliable encodingperformance, the HEDS-
5540/5640 and HEDM-5540 three channel encoders
require 2.7 kΩ (± 10%) pull-up resistors on output pins 2, 3,
and 5 (Channels I, A, and B) as shown in Figure 1. These pull-
up resistors should be located as close to the encoder as
possible (within 4 feet). Each of the three encoder outputs

can drive a single TTL load in this configuration. The HEDS-
5500, 5600, and HEDM-5500, 5600 two channel encoders
do not normally require pull-up resistors. However, 3.2
kΩ pull-up resistors on output pins 3 and 5 (Channels A
and B) are recommended to improve rise times, especially
when operating above 100 kHz frequencies.
