ASDA-
Using the encoder cable with shielding (double shielding is the best) is able to prevent voltage
coupling and eliminate the noise and interference from other electrical sources. Be sure to
observe the following steps to complete the shielding surrounding the encoder cable.
Revision September 2012
Chapter 3 Connections and Wiring
(1) Cut through the cable with the scissors and
make the metal core wires with shielding
exposed to a normal magnetic field. The
reserved core wire length should be
20~30mm. Then, cover a 45mm heat
shrink tube on the cable.
(2) Spread and trim the metal core wires with
shielding. Ensure to follow the table of CN2
Terminal Signal Identification to connect
the pins one by one.
(3) Leave a length of 5~10mm metal core wires
with shielding outside of the cable for the
installation of the metal saddle on the end.
The other unexposed wires of the cable
should be protected by heat shrink tube for
good ground contact.
(4) Install a metal saddle to cover the exposed
metal core wires. The metal saddle must
completely cover all the exposed metal
core wires. The connection between the
metal saddle and the metal part of the
connector on both ends of the cable should
be correct and well installed.
