Automotive Relay Definition
Automotive relays are provided in a design, production and quality structure that complies with the quality assurance system specified by each manufacturer, considering being installed in vehicles.
Automotive Relay Features
There are plug-in types that are directly attached to a vehicle such as an engine room, and printed circuit boards type that are mounted on a unit manufacturer's board.
Replaceable relays of the type having tab terminals for direct attachment to a vehicle connector or relay BOX.
Relay for printed circuit boards
It is of the type mounted on the printed circuit board of the unit manufacturer, and once mounted, it is not possible to replace the relay alone.
Automotive Relay Types
In order to cope with a variety of applications installed in vehicles, we have lined up of several external shapes and specifications suitable for each application.
- Lineup of products, mainly ISO types
- Lineup of small plug-in types specialized for specific applications
- Line-up of more compact products which are different from H-Bridge type which can normally and reversely control motor.
- Line up PCB relays that can replace plug-in relays
Automotive Relay Diagram
|Single type||There are two types of contact structures, SPST and SPDT.|
|Twin type||This is a relay with a reduced number of mounting steps by using a single relay in a single package.|
|H-Bridge types||The two SPDT single relays are packaged in one package, and the N.O. terminals and the N.C. terminals of the two single relays are shared, so that the relay is suitable for motor drive circuits.|
Automotive Relay Application Examples
Note for sale of Automotive relays and using catalogue
- Selling for car makers and companies related to Automotive
- Omron and car makers or companies related to automotive confirm relay specifications and actual using condition to use relays safely. Tests are included when necessary.
