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.
However, the user employs relays in
devices that fall within the scope this directive,
the user must also acknowledge the substances
prevented.
As this moment, none the aforementioned
directives require marking for all-or-nothing
relays3. applying the Directive components,
the Guidelines1 should consulted determine
whether the component question has "direct
function”.
2 Low Voltage Directive
Relays with terminals for printed boards/plug-and-
socket connections not come within the
purview the Low Voltage Directive. Electric motors, power supply units or
temperature controls represent examples such
components with "direct function”. Guidelines (version dated March 22, 2007) for the Application the Council Directive 2004/108/EC. The term includes solid state all-or-
nothing relays. They are therefore not subject the scope
of the Low Voltage Directive. In
the case electrical equipment which consi
dered basic component intended for incorpora
tion into other electrical equipment, the properties
and safety the final product will largely
dependent how integrated: such, these
components not fall within the Low Voltage
Directive and shall not marked. given relay may perform diffe
ring functions different devices.

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.Application the Directives All-or-Nothing Relays
1 EMC Directive
The EMC Directive concerns primarily the finished
products. Consequently,
all-or-nothing relays must considered compo
nents without "direct function” which are not
subject the EMC Directive.
Components which are integrated into device,
such relays, not have independent func
tion their own. These types of
components must provided with marking.
All-or-nothing they electro-mechanical relays
or solid state relays shall not labeled with a
CE marking nor shall declaration conformity
be issued within the scope the EMC Directive. Here again, safety function of
the individual application.
4 RoHS Directive
The substances prohibited the RoHS Directive
(Pb, Hg, Cd, Cr+6, PBB, PBDE) concern cate
gories devices that are mostly, but not entirely,
intended for private use.
2. Components such as
relays are not listed these categories. The Guide-
lines2 specifically cite electro-mechanical basic
components such connectors, relays with
terminals for printed circuit boards and micro swit
ches.
Consequently, marking shall not affixed
nor shall declaration conformity manufac
turer’s declaration issued under the Machinery
Directive.
The Low Voltage Directive concerns electrical
equipment intended for incorporation into device
as well equipment intended for direct use.
3 Machinery Directive
The Machinery Directive differentiates between
machines, machine parts and safety components.
The listing safety components Appendix is
conclusive and does not include relays.
Relays are not part any these categories. Therefore
they not directly fall within the scope this
directive. This writing deals exclusively with “non-specified-time all-or-nothing relays”. The abbreviated term “all-or-
nothing relay” has been introduced merely for purposes convenience. order adapt this situation in
good time, all Panasonic relays are generally
RoHS compliant. Guidelines (version dated August 2007) for the Application the Council Directive 2006/95/EC.
1. evaluating these
relays’ performance from the perspective the
Low Voltage Directive, the same conclusion is
reached with the printed board relay.
. such,
CE marking not mandatory for this type relay
