8.4 Determining Interconnect Cable Lengths
The following cable length charts are possible combinations for each side of example cascaded systems. All cables are
assumed to be 22 awg wire. Other lengths and combinations are possible; please call factory for assistance.
As the machine interface cable lengthens, the voltage drop increases, which results in shorter possible interconnect cables
to maintain supply voltage requirements at the cascaded sensor. See
Components on page 12 for a list of cordsets.

Example 1:
Machine Interface Cable (L1): 15 ft
Sensor Interconnect Cable (L2): 175 ft (Using one 100 ft and one 75 ft DEE2R cables) or 100 ft or shorter using single
cables
Example 2:
Machine Interface Cable (L1): 50 ft
Sensor Interconnect Cable (L2): 50 ft or shorter
