9.11 High Temp Cable
The 12-wire cable (XXX2CCB…) is used for wiring the sensor with the 24 VDC power supply, all
outputs, and the RS485 interface. The cable is Teflon coated and withstands ambient temperatures form
-80 to 200°C (-112°F to 392°F). Teflon coated temperature cables have good to excellent resistance to
oxidation, heat, weather, sun, ozone, flame, water, acid, alkalis, and alcohol, but poor resistance to
gasoline, kerosene, and degreaser solvents.
Power supply 2 wires (black/red)
Conductor: 0.3 mm² (AWG 22), 7x30 tinned copper
Isolation: FEP 0.15 mm wall (0.006 in)
Shield: none
RS485 interface 2 twisted pairs (black/white and purple/gray)
Conductor: 0,22 mm² (AWG 24), 7x32 tinned copper
Isolation: FEP 0.15 mm wall (0.006 in)
Shield: Aluminized Mylar with drain wire
Outputs and Ground 6 wires (green/brown/blue/orange/yellow/clear)
Conductor: 0,22 mm² (AWG 24), 7x32 tinned copper
Isolation: FEP 0.15 mm wall (0.006 in)
Shield: none
Cable diameter: 7 mm (0.275 in) nominal
Temperature: UL-rated at -80 to 200°C (-112°F to 392°F)
Further information for wiring the cable can be found in section 6.2 Electrical Installation, page 28.
High temp 12-wire cable can be purchased from the manufacturer in the following lengths:
4 m, 8 m, 15 m, 30 m, 60 m (13 ft., 26 ft., 49 ft., 98 ft., 197 ft.)
If you cut the cable to shorten it, notice that both sets of twisted-pair wires have drain wires inside their
insulation. These drain wires (and the white wire that is not part of the twisted pair) must be connected
to the terminal labeled CLEAR.
If you purchase your own RS485 cable, use wire with the same specifications as those listed above.
Maximum RS485 cable length is 1.200 m (4000 ft).
