MINIATURE SIGNAL RELAY
EB2 SERIES
COMPACT AND LIGHT WEIGHT
SURFACE MOUNTING TYPE
DESCRIPTION
The EB2 series is a version of the EA2 series, suitable for surface mounting. This series has three variations of
high solder joint reliability type, and low profile type.
FEATURES
Compact and lightweight : 7.5 mm × 14.3 mm × 9.3 mm, 1.5 g
2 form c contact arrangement
Low power consumption
Low magnetic interference
Breakdown voltage: 1 000 VAC (surge voltage 1 500 V), FCC Part 68 conformable
UL recognized (E73266), CSA certified (LR 46266)
Lineup in non-latch, single-coil latch and double-coil latch types
Lineup in minimum footprint (9.3 × 14.3), and high solder joint reliability (20 years) types
Lineup in low profile type (hight : 6.5 mm).
APPLICATIONS
Electronic switching systems, PBX, key telephone systems.
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/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.
Any special coil requirement, please contact NEC/TOKIN for availability.
