| DATA S H E E T MINIATURE SIGNAL RELAY EC2(ND),EE2(ND) SERIES High Insulation, High breakdown voltage, compact and lightweight, Surface mounting type DESCRIPTION NEC EC2 (ND) / EE2 (ND) series has based supplementary insulation for EN60950. (TUV Certified File No. R9750561) FEATURES TM Insulation distance : more than 2 mm TM Distance through insulation : more than 0.4 mm TM Applicable for the surge voltage standard of FCC (1500 V, 10 x 160 s) and BELLCORE (2500 V, 2 x 10 s) TM Two types for through-hole mounting (EC2 (ND) series) and surface mounting (EE2 (ND) series) APPLICATIONS Electronic switching systems, facsimile, modems, terminal 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.

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 100 mV, 100 A. This value is a reference value in the resistance load. Minimum capacity changes depending on swiching frequency and environment temperature and the load. 10 DATA SHEET ER0327EJ2V0DS00 EC2(ND),EE2(ND) SERIES DATA SHEET ER0327EJ2V0DS00 11 EC2(ND),EE2(ND) SERIES No part of this document may be copied or reproduced in any form or by any means without the prior written consent of 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 Conponents, 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 particular 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. |
