(2) Noise reduction products
(a) Data line filter (Recommended)
Noise can be prevented by installing a data line filter onto the encoder cable, etc. For example, the
ZCAT3035-1330 of TDK and the ESD-SR-250 of NEC TOKIN make are available as data line filters. As
a reference example, the impedance specifications of the ZCAT3035-1330 (TDK) are indicated below.
This impedances are reference values and not guaranteed values.
