Distribution enclosures with fine graded size adjustment
and individual enclosure openings for your application.
These enclosure ranges meet all the requirements for advanced
building automation. Their design variety allows you to also
solve individual requirements without any problems. The enclosure
size can also be adjusted to specific applications by fine
steps. Thus, the enclosure ranges cover all common widths
from 8.8 mm to 140 mm. Apart from conventional captive screw-type
terminals, cage clamps are also available for the device connection,
which allows for a very efficient device installation. And
if higher current intensities are possible, you can use heavy-duty
terminals up to a rated current of 50 A. For the connection
and communication with other devices and systems, a variety
of connectors are, of course, also available such as bus connectors,
KNX (EIB), RJ-45, etc. These enclosures are designed for both
top-hat-rail mounting and screwtype mounting
Connection system
Conventional, captive screw-type terminals, cage clamps, heavy-duty terminals and BUS connectors are possible. Two conductors can be connected to the same terminal. Non-used terminal points can be closed with blind plugs or moulded skins in the hood.
Solderable by machines
Mechanically solderable terminal blocks allow for an efficient soldering together with other components on PCBs. An additional stranded wire terminal is also possible.
Modularity
Widths from 8.8 mm to 140 mm allow for a fine graded size adjustment.
Two depth sizes
The switch cabinet enclosures of the KO 4900 range have a fitting depth of 97 mm.
PCB integration
Accommodation options for horizontal and vertical PCBs and any combinations of them provides more flexibility in the device design.
Module enclosures
These enclosures with a width of 70 mm or 140 mm can be equipped with one or two plug-type module enclosures with a transparent hinged front panel.
Many options:
Individual enclosure openings For an optimal customisation to specific requirements, it is possible to manufacture enclosures with individual openings, e.g. ventilation slots for better heat dissipation or for bus connectors.
Exchangeable front It protects adjusting and indicating elements and is available as a transparent version or in the colour of the enclosure.
Plug-type module enclosures Optional module enclosures accommodate PCBs and allow the replacement of complete functional units. Thus, these enclosures are perfect for the integration of fieldbus-ready devices. By the replacement of the module enclosure, it is easy to adjust the device to a fieldbus system.
Earthing spring
An optionally integrated earthing spring below the enclosure bottom provides for improved EMC properties. When the enclosure is snapped on the DIN rail, the PCB is automatically connected to the DIN rail.
