Furthermore, it complies with 2500 V surge-voltage requirement of Bellcore specification. FEATURES TM Compact and light weight TM 2 form c contact arrangement TM Low power consumption TM Reduced mounting space : 15 mm x 7.5 mm TM High-breakdown voltage of coil to contacts : 1500 Vac, 2500 V (rise time : 2 s, fall time : 10 s) TM Capable of High-power switching : 700 Vac, 4.2 A, 4 times in case of accident TM UL recognized (E73266), CAS certified (LR46266) APPLICATIONS Electronic switching systems, PBX, terminal equipment, telephone systems. 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.

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. Soldering should be done at 250 C within 10 sec. 4. Ultrasonic cleaning is not recommended to keep reliable contact performance. Alcohol based solvents are available as proper solvents. 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 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 antifailure 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. |
