MINIATURE SIGNAL RELAY
UA2/ UB2 SERIES
Super-com pact size, Slim -package, Surface m ounting type
DESCRIPTION
NEC's UA2/UB2 relay ia a new generation Miniature Signal Relay of super-com pact size and slim -pakage.
But, the latching type production is going to start after J une 2000.
FEATURES
™ Sm all m ounting size of slim package for dense m ounting.
™ 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 consum ption 140 m W
APPLICATIONS
Electronic switching system s, PBX, term inal equipm ent, telephone system , instrum ental equipm ent.
For Right Use of Miniature Relays
DO NOT EXCEED MAXIMUM RATINGS.
Do not use relays under exceeding conditions such as over am bient tem perature, over voltage
and over current. Incorrect use could result in abnorm al heating, dam age 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 inform ation in this docum ent is subject to change w ithout notice.

GUIDE TO APPLICATIONS
1. When connecting coils, refer to the pin configuration to prevent m isoperation or m alfunction.
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 recom m ended to keep contact perform ance reliable. Alcohol based solvents are
available as proper solvents.
4. Pressurized stress on the relay cover m ay affect reliable operation.
5. Minim um contact load of the relay is 10 m Vdc, 10 µA.
This value is a reference value in the resistance load.
Minim um capacity changes depending on switching frequency and environm ent tem perature and the load.

While NEC Corporation has been m aking continuous effort to enhance the reliability of its electronic
com ponents, the possibility of defects cannot be elim inated entirely. To m inim ize risks of dam age or
injury to persons or property arising from a defect in an NEC electronic com ponent, custom ers m ust
incorporate sufficient safety m easures in its design, such as redundancy, fire-containm ent, and anti-
failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based
on a custom er designated "quality assurance program " for a specific application. The recom m ended
applications of a device depend on its quality grade, as indicated below. Custom ers m ust check the
quality grade of each device before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment, au-
dio and visual equipment, home electronic appliances, machine tools, personal electronic equip-
ment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
system s, anti-crim e system s, safety equipm ent and m edical equipm ent (not specifically de-
signed for life support)
Specific: Aircrafts, aerospace equipm ent, subm ersible repeaters, nuclear reactor control system s, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
