Automotive Relay Market Segmentation Analysis

By Product Analysis:

The PCB segment dominated the automotive relay market in 2023. PCB (Printed Circuit Board) relays are essential to the automation and control procedures in the field of industrial applications.

The small size and space-saving design of PCB relays are among its main benefits. These relays' incorporation into industrial systems makes effective use of the space that is available. High temperatures, vibrations, and electrical disruptions are just a few of the harsh circumstances that these relays are designed to endure. Long-term cost reductions from the use of PCB relays in industrial applications can be substantial.

By Propulsion Analysis

The ICE segment held the largest share of the automotive relay market in 2023. As automakers embraced producing low-cost EVs, the top 10 selling models globally and in Europe changed towards hybrid vehicles and internal combustion vehicles despite the significant electrification trend. Internal combustion engines are predicted to have a significant market share due to the growing usage of ICEs in a variety of automotive and non-automotive applications in nations like China, Japan, and India. This will further drive the growth prospects of ICEs.

By Application Analysis:

Tthe convenience segment held the largest share of the automotive relay market in 2023. Automotive relays are commonly used in power window and door lock systems to regulate the functioning of motors that raise and lower windows. T

urning the lock and key on the door is one example. Relays regulate the high currents that these motors require. They provide convenience features as well as reliable and quick automobile entry control. Relays are essential parts of automotive security and safety systems because they control functions like airbag actuation.

By Vehicle Type Analysis:

The passenger car segment dominated the automotive relay market in 2023. All major global light vehicle markets have expanded, and this has led to a rise in automobile sales worldwide. Although just two major markets had double-digit growth in the first semester of 2024, the majority of the world's auto markets grew. These were Mexico and Brazil.

China continues to be the world's largest single-country new car market, with sales rising 3.3% to 9,856,000 vehicles in the first half of 2024. During the first half of 2024, 6878,400 new passenger vehicles were registered in Europe (EU, EFTA, UK), a 4.4% increase. Only 2.2% more new light cars were sold in the USA in the first half of 2024, reaching 7.8 million.
