KO4700
Enclosure
Series
Ideal for industrial applications. Small to large in size, KO4700
enclosures can accommodate 8 to132 terminals for field wire
connections. Series KO4700 enclosures can be customized to the
exact number of terminals required. Standard enclosures are
equipped with the maximum number of terminal strips and
terminals.The KO4700 series are available with two types of
terminations for connecting external wires. The Pressure Plate type
terminals,with a center line spacing of 9mm (.35 in.) and the Box
Clamp design, which has a 5mm (.19 in.) center line spacing for
much higher density.

The housing shell has molded printed circuit board
guides to save time when inserting printed circuit
boards, prevent misconnections and to keep the
boards from moving. Integral tabs on the bottom of
the shell further help to hold boards in place,
eliminating lateral movement. KO4700 housing
shells can be potted.
Printed circuit boards can be mounted in three ways:
Depending on the enclosure type,one board can be mounted directly
behind the front cover
(parallel
rail).Boards can also be
mounted
(parallel to the DIN rail) or
vertically (perpendicular to
the DIN rail). (Refer to the
Ordering Pages for board
patterns and location of
board guides.)
The housing cover snaps onto the housing shell. Two keyed tabs lock
the cover firmly in place. Removal of the cover is possible for service
and repair.
COVER DESIGNS
Single piece, tan color covers are typically used with the smaller
enclosures. They incorporate terminals and connections to the inside
of the enclosure. In some of the smaller enclosures, the cover doubles
as a plug.
A printed circuit board can be mounted directly behind the front
cover. This board is ideal for mounting components used for setting,
adjusting and monitoring such as switches, potentiometer, LEDs and
LCDs. There is no interferance with any other boards mounted within
the enclosure.
