Connectors Reduce Size of
CompoBus/S Remote I/O Terminals
1SRT2 terminals support both high-
speed communications (750 kbps) and
long-distance communications (500 m)
systems, switch selected
1Connectors simplify installation, reduce
wiring time
1Eight-point sensor connector models
and 16-point MIL connector models
1Saves space in control panels;
measures just 90 H x 32 W x 55 D mm
(3.54 x 1.26 x 2.17 inches)
1Mounts on DIN rail track; side- and
surface-mounting brackets optional

Note: 1. V terminals and G terminals are respectively connected internally.
When supplying power for I/O from communications connectors, power can be supplied to the sensor output devices from V
and G terminals.
2. When using an inductive load (solenoid, valve etc.), either use one with an internal reverse electromotive force absorption diode
or attach a diode externally.

Model Cable conductor size

XS8A-0442 0.14 to 0.2 mm2
Note: The XS8A-0441 or XS8A-0442 Connector is not provided
with the SRT2-VID or SRT2-VOD. Place an order for the
connector separately.
Cable Conductor Size Calculation Formula
Calculate the cable conductor size as follows.
The following information is given on each sensor cable:
Cable dia. (Number of conductors/Conductor dia.)
Conductor size (mm2)=
(Conductor dia./2)2xπx Number of conductors
Example: E3S-A
4 dia. (18/0.12)
Conductor size (mm2) = (0.12/2)2x3.14x1860.20
The conductor size is 0.2 mm2. Therefore, use the XS8A-0442.
