3-7-2. Sensor cable connection with special
grommet (450G-□-A version)
In order to seal multiple sensor cables into
EXAxt 450, a special grommet is provided that
is designed to accommodate one, two or three
sensor cables (5 mm dia.) plus a liquid earth
cable (2.5 mm dia.). In the pack with the grom-
met are blanking pieces to close any unused
holes. When correctly assembled, the grom-
met maintains the IP66 and NEMA 4X rating of
the EXAxt 450 housing.
Note! The special grommet is intended to be
used to seal the multiple cables from
the Yokogawa flow fittings such as
FF20.
