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.
• Correctly drill the board according
to the given board pattern

• Stick packaging also available for

• Unless otherwise specified, solder
under the following conditions
depending the type relay. seconds
• Please take caution with ulti-layer
boards. J
Be sure preheat before using
autom atic soldering. This could impair relay
performance. Relay performance may
degrade due the high thermal
