| w w at .D w DESCRIPTION The new NEC EX2/EX1 series is PC-board mount type and the most suitable for various motor and heater controls in the automobiles which require high quality and high performance. The EX2 series is succeeding in about 60% of miniaturization in comparison with the ET2 series. The EX1 series is succeeding in about 50% of miniaturization in comparison with the ET1 series. The EX2/EX1 series is under development now. Sh a et e 4U om .c DATA SHEET AUTOMOTIVE RELAYS EX2/EX1 SERIES FEATURES * PC-board mounting * Lead free solder is used * Approx. 75% relay volume of ET2 * Approx. 65% relay volume of ET1 * Approx. 60% relay space of ET2 * Approx. 50% relay space of ET1 * Approx. 88% relay weight of ET2 * Approx. 78% relay weight of ET1 APPLICATIONS * Motor control * Solenoid control 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 w w .D w t a S a e h t e U 4 .c m o EX2 SERIES EX1 SERIES For Proper Use of Miniature Relays Read the cautions described in NEC's "Miniature Relays" (ER0046EJ*) before dose designing your relay applications.
