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.
