What Is an Automotive Relay?
Automotive relay is literally relays designed for automotive circuit control, and there are many automotive relay for different applications.
Since each automobile manufacturer has its own circuit design, a variety of relays are manufactured and sold for each load in accordance with the automobile manufacturer's standards.
Recently, when repairing a circuit in the event of an automobile failure, it has become possible to quickly repair the circuit by replacing the failed automotive relay in the circuit module by module at once.
Uses of Automotive Relays
As the name suggests, "automotive relays" are used as relays for circuits related to the control of automobiles. There are many types of automotive relays, including relays used to control lamps such as headlights and taillights, and motor-related control relays used to operate power windows and door mirrors.
In addition, relays used to control air conditioners and rear-glass heaters, and those used in circuits required for battery charging are indispensable in the electrical circuits of automobiles.
Principles of Automotive Relays
Automotive relays has simple structure with a coil made of enameled wire and an iron core, and control electrical circuits by opening and closing contacts by sensing the current of an electromagnet.
There are various types of relays for automotive use. However, there is no special structure to a control relay, but one of its features is that it is lightweight.
The weight of an automobile affects fuel efficiency and driving performance. Although each automotive relays are lightweight, a large number of automotive relays are used in a single car, so the lighter the relay, the better.
Another advantage is low operating noise. Automotive relays used for motor control, such as power window operation, are often designed to be small and quiet. It is also important to make them suitable for each maker's model to enable mass production.
The Automotive Relays Market
Relays are used in a very wide range of fields, from factory automation to consumer and automotive applications.
Recently, demand for eco-friendly vehicles such as plug-in hybrids and electric vehicles has been increasing, partly under the banner of the decarbonized society set forth by Prime Minister Kan.
As a result, the market for automotive electronic components is expected to grow over the medium to long term. In particular, demand for automotive relays are increasing around the world, as they contribute to improving the ride quality of vehicles.
The global market for automotive relays are estimated to be worth $12.39 billion as of 2017.
It is expected to grow at an average annual growth rate of 6.2% through 2022, reaching $16.7 billion by the end of 2022.
