™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), and Ultra-low profile (hight : 5.6 mm)

APPLICATIONS

Electronic switching systems, PBX, key telephone systems, automatic test equipment and other electronic equipment.

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's "Miniature Relays" (ER0046EJ∗) when you choose relays for

your application.

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 mV, 10

A. This value is a reference value in the resistance load.

Minimum capacity changes depending on swiching frequency and environment temperature and the load.

NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this document.

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property

rights of third parties by or arising from use of a device described herein or any other liability arising from use of such

device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual

property rights of NEC Corporation or others.

While NEC Corporation has been making continuous effort to enhance the reliability of its electronic components, the

possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising

from a defect in an NEC electronic component, customers must incorporate sufficient safety measures in its design, such

as redundancy, fire-containment, 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 customer

designated "quality assurance program" for a specific application. The recommended applications of a device depend on

its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particu-

lar application.

Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual

equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots

Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-

crime systems, safety equipment and medical equipment (not specifically designed for life support)

Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, 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.
