      IP68 Motor
      Version Z9
All motor series from STÖGRA are available optionally with protection class IP68. The IP68 motors
are tested under water with 1 bar pressure (corresponds to operation of motor in 10m water depth).
Typical applications for IP68 motors are, beside underwater are any plants outside (e.g. faced to rain)
or in the food industry, where motors are cleaned with water. The motors include special sealings
and some special parts as special flanges). Options »brake« and »encoder« are also possible for
IP68 motors. IP68 motors need to be ordered with the extension »Z9« in the type designation.
