MINIATURE SIGNAL RELAY
EA2 SERIES
COMPACT AND LIGHTWEIGHT
DESCRIPTION
The EA2 series has reduced package size and power consumption to other NEC Conventional relays.
Furthermore, it complies with 1500 V surge-voltage requirement of FCC part 68 by the unique structure and the
efficient magnetic circuit
FEATURES
™
Low power consumption
™
Compact and light weight
™
2 form c contact arrangement
™
Low magnetic arrangement
™
Breakdown voltage : 1000 Vac (surge voltage 1500 V), FCC Part 68 compliant
™
Tube packaging
™
UL recognized (E73266), CAS certified (LR46266)
APPLICATIONS
Electronic switching systems, PBX, key telephone systems, automatic test equipment and other electronic equip-
ment.
ATTENTION
DO NOT EXCEED MAXIMUM RATINGS.
Do not use relays under exceeding conditions such as over ambient temperature, over voltage and over
current. Incorrect use could result in abnormal heating, damage to related parts or cause burning.
READ CAUTIONS IN THE SELECTION GUIDE.
Read the cautions described in NEC's "Miniature Relays" (ER0046EJ∗) when you choose relays for
your application.
