The slip ring produces a small EMF at high-speeds. To avoid increasing the EMF it is necessary to prevent
the rotating part from overheating the slip ring. Increasing the EMF can cause the vaporization of mercury
within the cells.
To ensure a long lifetime, it is recommended that the ROTOCON UHS Slip Rings are operated only within the
specified temperature range.
The small amount of mercury contained within the slip ring is only a minimum health risk because of the
confinement of the liquid metal within a hermetically sealed cell. The seal is guaranteed by PTFE seals even
at high speeds. Only extremely pure mercury is used in the manufacture of the ROTOCON UHS Slip Rings to
provide maximum conductivity.
These slip rings should not be stored for periods longer than one year. When not in use deposits of mercury
oxide can form within the cell causing increased resistance.
