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.

RELAY SOLDERING AND CLEANING GUIDELINES
In keeping with making devices compact,
it becoming more common weld the
relay board along with the
sem iconductors instead using the
previous plug-in type which relays
were plugged into sockets. Never use this
method.
The type protective structure will
determine suitability for automatic
soldering autom atic cleaning.
Use rosin-based non-corrosive flux.
• Preheat according the following
conditions. Solderability also improves. Relay performance may
degrade due the high thermal
capacity these boards. Note that the board is
pressed down hard enough, flux may
even penetrate flux-resistant type
relay.g.
• Correctly drill the board according
to the given board pattern

Keep the tip the soldering iron clean. Relay
performance cannot guaranteed if
the term inals are bent.
