KO4070

Enclosure

Series

Economical, compact KO4070 enclosures are supplied as easy to

assemble kits. They are ideal for housing I/O circuits, relays, timers

and other small devices. Each kit consists of two identical housing

half shells and 4 to 16 machine solderable terminals with standard

or extended length pins.

MATERIALS

Housing Shell: Polycarbonate, 10% Glass Filled

Terminal: Tinned Bronze

Terminal Screw: Chromated Steel

Temperature Rating:

125°C (257°F) UL94 VO

Standard Color: Light Gray

PROTECTION

KO4070 enclosures have an IP20 rating (finger protected) and

meet VBG4 and other European accident prevention requirements.

TERMINALS

Box clamp design terminal blocks are used with the KO4070

series enclosures. Wire(s) to be terminated are squeezed between

the bottom of the clamp and the busbar for reliable, gastight

connections. The terminal blocks can be machine soldered to the

board in the same step as the other components to save time and

labor. Enclosures with extended length pins are available to

increase enclosure cavity for large components.

All terminals have funnel shaped wire openings to eliminate wire

fraying. The terminal screws can be turned with a flat tip or a #1

or #2 Philips screwdriver.

MOUNTING

The KO4070 series have integral mounting feet that snap onto

standard 35mm DIN rail. They cannot be panel mounted.

MARKING

Silk screen or attach label to the face of the enclosure.

CONSTRUCTION

The KO4070 enclosures consist of two housing shells that snap

together, and sectional, snap-together terminals. The maximum

preassembled number of terminals are part of the enclosure kit.

Potting is not recommended. Enclosures with removable center

cover sections are available upon request.

BOARD PLACEMENT

Each enclosure can accept two boards, each up to 1.5mm (.0625

in.) thick, inserted vertically (parallel to the DIN rail) facing the

terminals. These boards can be machine soldered to the terminals.

Enclosure types KO4074 through KO4079, accept larger boards

that can be screwed to the sidewalls of the housing shells

(vertically, perpendicular to the DIN rail) using molded-in standoffs

and 2 screws. Boards mounted on the sides can be 1mm (.04 in.)

thick and require a wire jumper connection.
