Description
General notes
Series 44, a modular system of control units, offers the user numerous
combinations with its wide range of actuator elements for pushbuttons,
emergency-stop pushbuttons, rotary and keylock switches, interlocking
pushbuttons, potentiometer drives, illuminated pushbuttons and
indicators.
At the front the actuators feature an IP 65 protection class and can be
supplied with mat grey or mat chrome front rings.
The switching elements can be supplied for fitting on front adaptors or
for fitting on base adaptors, so that each control or indication point can
be made to fit the requirements of the most varied conditions of usage,
such as in industrial and mechanical engineering, marine and
rail-vehicle construction, systems engineering and the construction of
control mechanismus.
Series 44 is a high-quality product that has been manufactured and
tested according to the most up-to-date international regulation and
standards. Our products are marked with the CE sign in accordance
with the directive for low voltages.
Design
The system consists of actuators, front or base adaptors, switching
elements and lamp elements, pre-switching elements and lamp
transformers. The connection between the actuator elements and the
various function elements is done by means of a latch click-stop
connection through the front adaptor for front attachment.
For base attachment the various function elements are click-stopped on
to the base adaptor.
For pushbuttons with front attachment, further switching elements in the
2nd level can be click-stopped on to the 1st level of switching elements
(tandem arrangement).
Mounting
The control pushbuttons and indicators of Series 44 are designed to be
fitted in a mounting hole of 22.5 mm diameter in accordance with IEC
60947-5-1 and VDE 0660. The actuators can be inserted in mounting
holes with or without recess for the anti-twisting device and are
self-holding with means that they can be fitted quickly and easily in the
front panel (one-person fitting).
When the actuator elements are installed in metallic front panels and
housings, they should not be incorporated in the protection provision.
When installed in insulated housing, the "protection insulation"
provision is preserved.
Terminals
All function elements have shockproof screw terminals (finger safety in
accordance with DIN VDE 0106, part 100 and VBG 4) and have
openings to guide a screwdriver. When delivered, the screw terminals
are open, thus guaranteeing safe and fast installation.
The lamp transformer has srew terminals as primary-terminal and as
secondary connection connecting leads with multi-core cable ends.
The designation for terminal connections accords with DIN EN 50013.
Marking
The marking plate for illuminated pushbuttons, indicators or markable
pushbuttons can be provided with pictograms conforming to ISO-R 369
or with lettering.
For further information about engraving, hot stamping and film inserts
see part Marking.
Illumination
Incandescent lamps or Single-Chip LEDs with BA9s lampholder assure
perfect illumination of the indicators and illuminated pushbuttons.
Luminosity and wave length scattering caused by the technology used
in the LED manufacturing processes may lead to visual differences in
our products.
