Electrical Interface
To insure reliable encoding performance, the HEDS-9040
and 9140 three channel encoder modules 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 mod-
ule as possible (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 HEDS-9040 and HEDS-9140. The
Aligning Recess Centers must be located within a toler-
ance circle of 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).
