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.

CONFIGURATION AND CONSTRUCTION
PROTECTIVE CONSTRUCTION
1. e
Relay which turns when the coil is
energized and turns off when de
energized. The relay set reset by
alternately applying pulse signals the
same polarity. harmful
gas humidity will ever reach the
contacts. ith one coil, the relay set or
reset applying signals opposite
polarities. e
Relay with latching construction
composed coils: set coil and reset

*Since the plastic breathes, please not use atm osphere that contains silicone.
W recommend hand soldering, because
these relays are not constructed to
prevent flux and cleaning fluid from
entering during autom atic soldering
