APPENDIX 139
9 Press all of the connector parts together. read the strain relief onto the back shell.
10 Tighten the strain relief screws on the back.

Appendix B – Cable Lengths
Maximum cable lengths are dependent on both power and communication requirements.
In some cases, it may be benecial to use wire pairs, normally designated for communica-
tions, for power instead. is may make sense in applications where only one communica-
tion port is needed. In this case, you can extend the distance of power by adding a commu-
nication wire pair to the power wire pair. In addition, since the power requirements for the
SmartSensor Advance model SS200V are lower than those for the SmartSensor Advance
model SS200, the maximum cable lengths are longer.
Maximum Cable Length for Powering SS200V
e following recommendations allow you to provide reliable power to the SmartSensor.
e SmartSensor cables red and black wires provide a 20 AWG wire pair. e other pairs on
the SmartSensor cable are 22 AWG and are normally used for communication.
e table below shows the cable lengths for power when using a SmartSensor Advance
model SS200V (see Table B.1):
Cable Gauge 24 Volts 12 Volts
20 AWG (6-conductor) 1500 ft. (457.2 m) 300 ft. (91.44 m)
Add 485+/485- (6-conductor) 2450 ft. (746.76 m) 500 ft. (152.4 m)
14 AWG 6500 ft. (1.98 km) 1300 ft. (396.24 m)
12 AWG 9000 ft. (2.74 km) 1800 ft. (548.64 m)
10 AWG 13700 ft. (4.18 km) 2800 ft. (853.44 m)
Table B.1 – Maximum Cable Length for Power (model SS200V)
If the cable length is longer than 1500 . (457.2 m) when operating at 24 V, it is possible to
increase the maximum cable length by wiring a pair of lines normally used for RS-485 com-
munications with the red and black wires.
