Note: The tolerance requirements are on the mating shaft, not on the codewheel.
Electrical Interface
To insure reliable encoding performance, the HEDT-9040
and 9140 three channel encoder modules require 2.7
kW (± 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 in close proximity of the
encoder module (within 4 feet). Each of the three encoder
module outputs can drive a single TTL load in this con-
fi guration.
Mounting Considerations
Figure 2 shows a mounting tolerance requirement for
proper operation of the HEDT-9040 and HEDT-9140. The
Aligning Recess Centers must be located within a tolerance
circle of 0.13 mm (0.005 in.) radius from the nominal
locations. This tolerance must be maintained whether the
module is mounted with Side A as the mounting plane
using aligning pins (see Figure 5), or mounted with Side
B as the mounting plane using an alignment tool (see
Figures 3 and 4).
