DATA SHEET
MINIATURE SIGNAL RELAY
EC2/EE2 SERIES
RoHS Compliant
COMPACT SIZE, SLIM-PACKAGE
DESCRIPTION
NEXEM EC2/EE2 relay is a standard miniature signal relay, compact and slim.
FEATURES
□ Compact and light weight
□ FCC (1500 V) and Telcordia (2500 V) surge capacity
□ UL recognized and CSA certified.
□ Low power consumption (100-200 mW)
□ ND type (High insulation) conform to supplement insulation for EN60950
□ NKX type (High breakdown voltage) can withstand 1.5KVAC at open contacts
APPLICATIONS
Electronic switching systems, PBX, Terminal equipment, Telephone system
For Right Use of Miniature Relays
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 EM Devices' "Miniature Relays" when you choose relays for your application.
