Rotary Encoders:
The KE-USB108 features two 4 position interface connectors which
accept phased signals from a device such as a rotary encoder
switch.
Power is supplied to the rotary encoder switch from the
KE-USB108 for 5 volt operation only. This interface is compatible
with mechanical and/or optical rotary encoder switches.
Use
our
cable to help connect from
the KE-USB108 to a rotary
encoder switch.
Use the diagram to the
right to make a connecting
cable for a rotary encoder
switch.
The KE-USB108 unit accepts input from mechanical and/or
optical rotary encoders that produce a quadrature signal.
NOTE: Do not supply power to the rotary encoder switch interface connector.

Typical Quadrature Signals
from a Rotary Switch
A2 = 2nd Rotary Sw. A Input
5V = Power for 2nd Rotary Sw.
GND = GND for 2nd Rotary Sw.
B2 = 2nd Rotary Sw. B Input
A1 = 1st Rotary Sw. A Input
5V = Power for 1st Rotary Sw.
GND = GND for 1st Rotary Sw.
B1 = 1st Rotary Sw. B Input
