NOTE
• For excitation cable and power cable, always use a
crimp terminal with an insulation cover.
• Use crimp tools supplied by the manufacturer of the
crimp terminal you want to use to connect the crimp
terminal and cable.
• Use crimp tools that are appropriate for the diameter
of the cable to be connected.

Figure 4.2.2 Dedicated Signal Cable
The flow signal is transmitted via this dedicated cable.
The cable is constructed with double shielding over the
two conductors, and heat-resistant vinyl is used for the
outer jacket material.
Finished diameter: 10.5 mm (0.413 in.)
Maximum length:
Combination with the AXG1A/AXFA11 transmitter:
200 m (660 ft)
Combination with the AXW4A transmitter:
100 m (330 ft)
Maximum temperature: 80°C (176°F)
IMPORTANT
If the cable is longer than required, cut off any extra
length rather than coiling it up, and terminate the
conductors as shown in Figure 4.2.3.
Avoid using junction terminal boards to extend the cable
length, as this will interrupt the shielding.
