Compatible Devices Section 1-3
The communications distance depends on the cable used, as follows:
Note When 4-conductor VCTF cable or Special Flat Cable is used to connect fewer
than 16 Slaves, the main line can be up to 100 m long and the total branch
line length can be up to 50 m in High-speed Communications Mode. (These
are the same conditions as when 2-conductor VCTF cable is used.)

Connector Model Comments
Branch Connector SCN1-TH4 Use this connector to create a branch line
from the main line.
(Used with Special Flat Cable only.)
Extension Connector SCN1-TH4E Use this connector to extend the Special Flat
Cable.

Connectors with Cable with a
socket and plug
XS2W-D42@-@81-@ Connectors with cable used to connect the
Water-resistant Terminal to a T-joint.
Can be used as a power supply cable (with
the female socket connected to the Water-
resistant Terminal).
Can be used as an I/O cable for sensors that
have connectors (with the male plug con-
nected to the Water-resistant Terminal, if the
product has a model number suffix “A”).
Connector with Cable with a
female socket
XS2F-D42@-@80-@ A connector with cable used to connect the
Water-resistant Terminal to a T-branch con-
nector.
Can be used as a power supply cable (with
the female socket connected to the Water-
resistant Terminal) and the other end wired to
a commercially available terminal block.
Connector with Cable with a
male plug
XS2H-D421-@80-A A connector with a cable used to connect the
Water-resistant Terminal to an I/O device.
Can be used as an I/O cable (with the male
plug connected to the Water-resistant Termi-
nal) and the other end wired to the I/O device.
