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

CE marking not mandatory for this type relay. They are
therefore not subject the scope the Low

components must provided with marking. order adapt this situation good
time, all Panasonic relays are generally RoHS
compliant. The abbreviated term “all-or-nothing
relay” has been introduced merely for purposes convenience.

Relays with terminals for printed boards/plug-and-
socket connections not come within the purview
of the Low Voltage Directive. the

do not fall within the Low Voltage Directive and

All-or-nothing they electro-mechanical relays
or solid state relays shall not labeled with Ce

the Guidelines1 should consulted determine
whether the component question has "direct

As this moment, none the aforementioned
directives require marking for all-or-nothing
relays3. Guidelines (version dated August 2007) for the Application the Council Directive 2006/95/EC.
The Low Voltage Directive concerns electrical
equipment intended for incorporation into device
as well equipment intended for direct use.
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.
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. This writing deals exclusively with “non-specified-time all-or-nothing relays”. Consequently,
all-or-nothing relays must considered compo
nents without "direct function” which are not subject
to the EMC Directive.

Components which are integrated into device,
such relays, not have independent func

they not directly fall within the scope this
directive.
Consequently, marking shall not affixed

Relays are not part any these categories.
3 Machinery Directive
The Machinery Directive differentiates between
machines, machine parts and safety components. Electric motors, power supply units or
temperature controls represent examples such
components with "direct function”. However, the user employs relays in
devices that fall within the scope this directive,
the user must also acknowledge the substances
prevented. Guidelines (version dated March 22, 2007) for the Application the Council Directive 2004/108/EC.Application the Directives All-or-Nothing Relays
1 EMC Directive
The EMC Directive concerns primarily the finished
products. The term includes solid state all-or-nothing
relays. Here again, safety function of
the individual application. The Guidelines2 specifi
cally cite electro-mechanical basic components
such connectors, relays with terminals for
printed circuit boards and micro switches. Components such as
relays are not listed these categories.
