K70
Enclosure
Series
The K70 series enclosures are small to medium in size and offer
cost effective solutions for many applications.
They can accommodate 8 to 32 terminals for field wire
connections. Pressure plate terminals are standard with both the
fixed and pluggable versions.

PROTECTION
K7O enclosures have an IP10 rating (hand protected). By using
optional terminal covers the protection rating can be increased
to IP20 (finger protected). VBG4 and other European accident
prevention requirements are met.
CONSTRUCTION
The K70 enclosures are supplied as unassembled kits.
Each kit consists of a housing shell and a snap-on cover,
complete with integral terminals and terminal-to-board
connection provisions. Integral printed circuit board guides are
molded into the housing shell to save time when inserting
boards, to prevent misconnections and to keep the boards in
place. Integral tabs on the bottom of the shell further help to
hold the boards in place and eliminate lateral movement and
warpage.
Printed circuit boards can be mounted in three ways:
• Vertically
• Horizontally
• Behind the Front Cover
Boards can be placed vertically (perpendicular to the DIN rail)
and/or horizontally (parallel with the DIN rail). Enclosures with
plug-in covers can accept an additional board mounted directly
behind the front cover. This board is ideal for mounting
indicating devices such as LEDs, LCDs for monitoring, switches
and potentiometers for setting and adjusting purposes. The
housing cover snaps onto the housing shell. Two tabs lock the
cover firmly in place. Removal of the cover is possible for service
and repair. Potting is possible.
The K70 housing covers have external and internal barriers
between terminals to increase creepage distance and to help
prevent accidental touching of live potentials that may be
present. Optional terminal covers that decrease the size of the
opening are available as accessories.

TERMINALS
Pressure Plate terminals with either fixed or pluggable terminal-
to-board connections are offered in the K70 enclosures. The
pressure plate, which is captive to the terminal screw,
automatically rises when the screw is loosened. One or two
wires of equal or different sizes up to 2.5mm
2
(14 AWG) can be
terminated in each terminal. The grooved corners of the
pressure plate ensure positive wire retention. The flat bottom of
the terminal extends to the inside of the enclosure and provides
the terminal-to-board connection. The terminal screws can be
turned by a flat tip or a #2 Phillips screwdriver.
Upon request, terminals can be loaded in selected positions
only.
For better retention,
the plug-in type
covers have captive
screws at the corners
that insert into brass
bushings, molded
into the housing
shell. The pluggable
versions are ideal
whenever quick
connections and
replacement are
important. They also
reduce the danger of
misconnected wires
and downtime.
MOUNTING
The K70 Enclosures mount easily by snapping onto standard
35mm DIN Rail. Many can also be panel mounted using corner
mounting holes which accept two M4 or M5 (#6 or #10)
screws. These mounting holes are molded into two corners of
the housing shell base and do not increase the height or width
of the enclosure, thus insuring a compact, high density
arrangement when multiple enclosures are installed adjacent to
each other. Enclosure types K7022.5A, K7022.5B and
K7022.5C have two integral pull-out tabs on the base of the
enclosure for panel mounting. (Refer to Enclosure Mounting
Procedures on page 19.)
MARKING
The K70 enclosures have an area on the front of the cover for
marking and mounting of components such as switches,
potentiometers, LEDs or LCD indicators. Custom imprinted
plates can be inserted as well, allowing imprinting of plates
separate from the enclosure, reducing cost and delays.
ACCESSORIES
• 35 x 7.5 mm DIN Rail
• Terminal Covers
• Pull-Out Panel Mounting Tabs.
TERMINAL-TO-BOARD CONNECTIONS
The K70 series offers fixed and pluggable terminal-to-board
connection possibilities.
Fixed Connections
Fixed terminal-to-board connections can be made by Wire
Jumper, Fast On tabs or Machine Solderable Pins (K7022.5C
only).
Fast On
tabs, (2.8 x 0.8 mm) accept industry standard Fast On
connectors crimped onto wire jumpers.
Wire Jumper
connections can also be made by soldering a
wire jumper between the center holes of the Fast On tab and
the printed circuit board(s).
Machine Solderable
Pins
(offered only with type
K7022.5C) can be removed from the enclosure and machine
soldered to the board in the same step as other components,
saving assembly time.
Pluggable Connections
Pluggable terminal-to-board connections are made by using
Card Edge
connectors. They are an integral part of the covers
of K7075P, K70100P and K70150P and plug directly onto the
board(s).
Solder Pins
are also provided in these enclosures for
terminal-to-board connections when mounting an additional
board directly behind the front cover. A
Wire Jumper
can be
soldered to these pins as well.
CUSTOMIZATION
Enclosures can be
customized with cutouts
and holes for
potentiometers, switches,
LEDs, LCDs and other
devices. Using state of the
art machining, we can
punch, drill or cut to your
most exacting
specifications. Custom
colors and special markings
are also available. Please let
us know what your
requirements are.
