DATA SHEET
MINIATURE SIGNAL RELAY
UA2/UB2 SERIES
Super-compact size, Slim-package, Surface mounting type
DESCRIPTION
NEC's UA2/UB2 relay ia a new generation Miniature Signal Relay of super-compact size and slim-pakage.
But, the latching type production is going to start after June 2000.
FEATURES
Small mounting size of slim package for dense mounting.
Bellcore (2500 V) and FCC (1500 V) surge capability.
IEC950/UL1950/EN60950 spacing and high breakdown voltage.
(Basic insulation class on 200 V working voltage)
Low power consumption 140 mW
APPLICATIONS
Electronic switching systems, PBX, terminal equipment, telephone system, instrumental equipment.
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's "Miniature Relays" (ER0046EJ) when you choose relays
for your application.
The information in this document is subject to change without notice.

UA2/UB2 SERIES
GUIDE TO APPLICATIONS
1. When connecting coils, refer to the pin configuration to prevent misoperation or malfunction.
2. The latch type relay should be initialized at the appointed position (set or reset position) when using, and should
be energized or deenergized to the specified polarity to avoid wrong operations by reversed contact state.
3. Ultrasonic cleaning is not recommended to keep contact performance reliable. Alcohol based solvents are
available as proper solvents.
4. Pressurized stress on the relay cover may affect reliable operation.
5. Minimum contact load of the relay is 10 mVdc, 10 µA.
This value is a reference value in the resistance load.
Minimum capacity changes depending on switching frequency and environment temperature and the load.
