DATA SHEET AUTOMOTIVE RELAYS ET2/ET1 SERIES DESCRIPTION The new NEXEM ET2/ET1 series is PC-board mount type automotive relay suitable for various motor and heater control applications that require a high quality and performance. The ET2/ET1 series is the relay that succeeds fundamental structure and performance of the NEXEM EP2/EP1 series that has the high share with a motor control usage of the automobile of the world. Besides the ET2/ET1 series is succeeding in about 50% of miniaturization in comparison with the EP2/EP1 series. FEATURES * PC board mounting * Approx. 50% relay volume of EP2/EP1 * Approx. 75% relay space of EP2/EP1 * Approx. 70% relay height of EP2/EP1 * Approx. 50% relay weight of EP2/EP1 APPLICATIONS * Motor control * Heater control * Solenoid control Type ET2 Type ET1 For Proper Use of Miniature Relays DO NOT EXCEED MAXIMUM RATING. Do not use relay under excessive conditions such as over ambient temperature, over voltage and over current. Incorrect use could result in abnormal heating and damage to the relay or other parts. READ CAUTIONS IN THE SELECTION GUIDE. Read the cautions described in EM Devices' "Miniature Relays" before dose designing your relay applications.

No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of EM Devices Corporation or others. While EM Devices 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 EM Devices electronic component, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. EM Devices' products 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 EM Devices' products are "Standard" unless otherwise specified in EM Devices' Data Sheets or Data Books. If customers intend to use EM Devices' products for applications other than those specified for Standard quality grade, they should contact an EM Devices sales representative in advance. (Note) (1) "EM Devices" as used in this statement means EM Devices Corporation and also includes its majorityowned subsidiaries. (2) "EM Devices electronic component products" means any electronic component product developed or manufactured by or for EM Devices (as defined above).
