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.

If relay and magnetic switch are
mounted next each other single
plate, the relay contacts may separate
m entarily from the shock produced
when the agnetic switch operated
and result faulty operation.

operation. This particularly likely
to happen when being transported by

on separate plates, using rubber sheet
to absorb the shock, and changing the

• The plastic becomes brittle the switch
is exposed low tem perature, low
humidity environm ent for long periods
of time. Note that when silicone used near
relay, switching the contacts the
presence its gas causes silicone to
adhere the contacts and may result in
contact failure (in plastic sealed types,
too). you remove any relays from
the tube packaging, sure slide the
stop plug one end hold the
remaining relays firm together they
would not move the tube.

In addition, when transporting storing
relays while they are tube packaged,
there are cases when the tem perature
may differ from the allowable range. For this reason, when a

other large relay, transformer, speaker
is located nearby, the relay
characteristics may change and faulty
operations may result.
In this situation, sure consult the
individual specifications.
