Direction of Motor Rotation
When the codewheel rotates in a counter-
clockwise direction, channel A will lead channel
B (Figure 1 illustrates the definition of clockwise
direction of codewheel rotation). When the
codewheel rotates in a clockwise direction,
channel B will lead channel A.

Line Receiver or compatible as line receiver.
Unused pin should be grounded for noise
reduction. Shielded Cable should be used for
better noise immunity.
Mating Connector
AEDA-3300 requires a 5 x 2 (1.27 mm x 1.27
mm) female IDC Connector. The cable used is
0.635 mm pitch flat ribbon cable.
