EE2 SERIES
Compact and lightweight, High breakdown voltage,
Surface mounting type
DESCRIPTION
The EE2 series surface-mounting type sustaining high-performance of NEC TOKIN EC2 series.
FEATURES
Compact and light weight
2 form c contact arrangement
Low power consumption
Reduced mounting space : 15 mm × 9.5 mm
High-breakdown voltage of coil to contacts : 1500 Vac, 2500 V
(rise time : 2 µs, fall time : 10 µs)
Low power consumption : 100 to 140 mW
Capable of High-power switching : 700 Vac, 4.2 A, 4 times in case of accident
NK type guarantee 1.5kVac over withstanding voltage at open contact. (Only make contact)
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 NEC/TOKIN's "Miniature Relays" when you choose relays for your application.

The latch type relays should be initalized at appointed position before using, and should be enegized to specific polanity
by a bone polabity to avoid wrong operation.
