Modular covers consist
of a one-piece tan frame
with matching flat front
panel. Some versions
have a front cover panel
that is removable and
offered in matching tan
or clear.The front covers
can be custom imprinted
or marking plates can
be produced and installed behind the transparent front cover panel.
TERMINAL DESIGNS
Select from Pressure Plate or Box Clamp terminals with wire
protectors, and fixed or pluggable terminal-to-board connections.
(Please refer to the Ordering Pages). Removable fixed or pluggable
terminal strips can be replaced by terminal plugs if not all of the
external connections of the standard enclosure are needed. The
terminal screws used with both the pressure plate and box clamp
designs can be operated with a flat tip or a #1 or #2 Philips type
screwdriver.
Pressure Plate Termination
This type of terminal consists of a pressure
plate (captive to the terminal screw) and
the terminal bottom. The pressure plate
rises automatically when the screw is
loosened. One or two wires, of equal or
different sizes up to 2.5mm
can be terminated. The grooved corners
of the pressure plate ensure positive
retention of wire(s). The flat bottom of the
terminal extends to the inside of the
enclosure and connects the terminal to the
board(s) inside.
Box Clamp Termination
The box clamp terminal accepts wires up to 4mm
When the terminal screw is tightened, the serrated bottom of the wire
protector pushes the wire to be terminated against the serrated
busbar. The busbar extends to the inside of the enclosure to provide
the terminal-to-board connection.
TERMINAL-TO-BOARD CONNECTIONS
The KO4700 Series offers fixed and pluggable terminal-to-board
connection possibilities. (Please refer to the Ordering Pages on the
following pages for your selection.)
Fixed Connections
Fixed terminal-to-board connections can be made by Wire Jumper,
Fast On tabs, Solder tabs, or Machine Solderable Pins.

connectors. Use with
wire jumpers to connect
to board(s).
Wire Jumper
connections can also
be made by soldering
a wire jumper between
the center hole of the
Fast On tab and the
printed circuit board(s).

board in the same step as the other components, saving assembly
time. The metal parts of the terminals are supplied as separate strips
which snap into the terminal housing after soldering.
Pluggable Connections
The pluggable terminal strips of the KO4700 series fit across the
width of the enclosure and plug directly into the board(s) by using a
Card Edge connector. Enclosures equipped with pressure plate
terminals also provide Solder Tabs for terminal-to-board connections
when mounting an additional board directly behind the front cover.
A Wire Jumper can be soldered to these tabs as well.
For better retention, the strips have captive screws at each end that
insert into brass bushings, molded into the housing shell. Up to four
terminal strips can be used per enclosure.The pluggable versions are
ideal whenever quick connections and replacement of boards and
devices is important. They also reduce the danger of misconnected
wires and downtime.
MOUNTING
The KO4700 Series enclosures are designed to be mounted on
standard 35 x 7.5mm DIN rail but will also fit on the 35 x15mm
DIN rail. The extra high enclosures should be mounted on the
deeper, 35 x 15mm DIN rail. (Refer to the Ordering Pages on the
following pages to determine the correct size rail for the enclosure
you select.)
KO4700 series enclosures
can also be panel mounted
using pull-out tabs on the
base of the enclosure. One
tab is factory installed on
each enclosure. Up to a
total of 6 pull-out mounting tabs can be installed (See Accessories)
(Refer to page 19 for mounting instructions.)
MARKING
KO4700 enclosures have a flat center area on the cover for marking
and mounting of components. Several types have removable front
cover panels, which can be marked at a separate location.
Imprinted marking plates can be used in conjunction with the
transparent, removable cover panel.
ACCESSORIES
CUSTOMIZATION
Enclosures can be customized to the
exact number of terminals needed.
We can punch, drill or cut custom
cutouts and holes for potentiometers,
switches, LEDs or LDCs. Custom
colors and special markings are
also available. Please call us for
further information.
