Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.
The Guidelines2 specifi
cally cite electro-mechanical basic components
such connectors, relays with terminals for
printed circuit boards and micro switches. This writing deals exclusively with “non-specified-time all-or-nothing relays”.
1. However, the user employs relays in
devices that fall within the scope this directive,
the user must also acknowledge the substances
prevented.Application the Directives All-or-Nothing Relays
1 EMC Directive
The EMC Directive concerns primarily the finished
products.
All-or-nothing they electro-mechanical relays
or solid state relays shall not labeled with Ce
marking nor shall declaration conformity be
issued within the scope the EMC Directive.
The Low Voltage Directive concerns electrical
equipment intended for incorporation into device
as well equipment intended for direct use. Here again, safety function of
the individual application. The abbreviated term “all-or-nothing
relay” has been introduced merely for purposes convenience. They are
therefore not subject the scope the Low
Voltage Directive.
Components which are integrated into device,
such relays, not have independent func
tion their own. the
case electrical equipment which considered a
basic component intended for incorporation into
other electrical equipment, the properties and
safety the final product will largely dependent
on how integrated: such, these components
do not fall within the Low Voltage Directive and
shall not marked. Therefore
they not directly fall within the scope this
directive. given relay may perform diffe
ring functions different devices.
3 Machinery Directive
The Machinery Directive differentiates between
machines, machine parts and safety components.
2.
Except for larger relays which may, for example,
find application switching cabinets, the same
considerations apply common-place relays with
plug-in connections available also with printed
board terminals.
Consequently, marking shall not affixed
nor shall declaration conformity manufac
turer’s declaration issued under the Machinery
Directive. applying the Directive components,
the Guidelines1 should consulted determine
whether the component question has "direct
function”. These types of
components must provided with marking. The
listing safety components Appendix is
conclusive and does not include relays. Components such as
relays are not listed these categories. Consequently,
all-or-nothing relays must considered compo
nents without "direct function” which are not subject
to the EMC Directive. Electric motors, power supply units or
temperature controls represent examples such
components with "direct function”. order adapt this situation good
time, all Panasonic relays are generally RoHS
compliant.
3.
Relays are not part any these categories.
2 Low Voltage Directive
Relays with terminals for printed boards/plug-and-
socket connections not come within the purview
of the Low Voltage Directive.
4 RoHS Directive
The substances prohibited the RoHS Directive
(Pb, Hg, Cd, Cr+6, PBB, PBDE) concern catego
ries devices that are mostly, but not entirely,
intended for private use. evaluating these
relays’ performance from the perspective the
Low Voltage Directive, the same conclusion is
reached with the printed board relay. The term includes solid state all-or-nothing
relays. Guidelines (version dated March 22, 2007) for the Application the Council Directive 2004/108/EC.
As this moment, none the aforementioned
directives require marking for all-or-nothing
relays3. such,
CE marking not mandatory for this type relay. Guidelines (version dated August 2007) for the Application the Council Directive 2006/95/EC.
