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
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.
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).

Machine Solderable Pins

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

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.
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.
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.
