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.
Contact Bounce (Time)
Generally expressed time (ms), this
refers the intermittent switching
phenomenon the contacts which
occurs due the collision between the
movable metal parts contacts, when
the relay operated released. (With multiple pole devices the
time until the last contact closes. Vibration Resistance
1) Functional
The vibration which can tolerated by
the relay during service, without causing
the closed contacts open for more than
the specified time. Shock Resistance
1) Functional
The acceleration which can tolerated
by the relay during service without
causing the closed contacts open for
more than the specified time. Insulation Resistance
The resistance value between all
mutually isolated conducting sections of
the relay, i.

1. Release Time
The elapsed time from the initial removal
of coil power until the reclosure the
Form (normally closed) contacts (last

Dielectric Strength)
The maximum voltage which can be
tolerated the relay without damage for
a specified period time, usually
measured the same points as
insulation resistance. Expressed an

The elapsed time from the initial

across open contacts and between coil or
contacts any core frame ground
