CMS Flat Cable
The CMS flat cable is a 4-pin cable for connecting multiple sensors to one control unit. The cable
is available in the following four lengths: 2m (CMS-800), 5m (CMS-802), 10m (CMS-803),
and 30m (CMS-805).
Please take into account the following information on the possible cable length of the CMS flat cable
depending on the number and shape of sensors:

• Do not exceed a total flat cable length of 32m for all CMS-Bus lines for each control unit.
•
Flat cables longer than approx. 15m could require a 120Ω terminating resistor between the two inner
wires at the far end.
• For the flat cable, please consider:
- Use within closed housings only
- Keep a distance of min. 5.5 mm to uninsulated live parts
- Where necessary, additional protection against mechanical stress or UV radiation must be ensured.
