AUTOMOTIVE RELAYS
ET2/ET1 SERIES
DESCRIPTION
The new NEC 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 NEC 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 NEC’s “Miniature Relays” (ER0046EJ) before dose designing your relay
applications.
