Market Overview

The automotive relay market is expected to register a CAGR of  over 5.2%, during the forecast period, 2020 - 2025.

  • Relays in automotive have been in existence since electronics were introduced, and their numbers are still on the rise, due to the increasing electrification of vehicles.
  • Along with vehicle electrification, factors, such as increasing trend toward safety, fuel efficiency standards, and stringent emission norms, have also been driving the market growth.
  • Rapidly growing use of electric components in the current and upcoming vehicles is consistently propelling the need for manufacturing reliable and standardized components, for efficient and safe and secure switching of electric loads. As a result, solid-state plug-in relays have gained significant market demand in the automotive industry, due to their longer service life (i.e. several million switching cycles) than electromechanical type relays.

Scope of the Report

Relay acts as a switch and used to switch connections between different circuits. Relays consist of an electromagnet, wherein the input current causes the coil to generate a magnetic field, which causes the contacts to meet, and thus, the circuit is established. If the input voltage is insufficient, then the contacts may not come together, due to the weak magnetic field. Among relay types, PCB relay and plug-in relay are two major types of automotive relays that have been considered in the scope of the market.

The automotive relay market has been segmented by type, application type, and geography.

Key Market Trends

Plug-in Relay to Witness Fast Growth

Currently, the demand for solid-state relays, especially solid-state plug-in relay, is growing, as they can handle high-rated currents (50A-80A) and operating voltages (less than 400V), similar to that of electromechanical type relays. Additionally, plug-in relay’s simple design structure and lightweight nature make them suitable as a close replacement for heavy electromechanical type relays.

A solid-state plug-in relay is deployed in various application fields of automobiles, such as electrically heated catalytic converters, motors and pumps, and body electronics, like door locks, seat controls, window lifters, etc.

Moreover, plug-in relays are also available in three major operating characteristics with current carrying capacities of 30A, 40A, and 70A.

ABS controls are one of the prominent areas of applications for plug-in relays in the automotive market.

Competitive Landscape

The market for automotive relay is highly competitive, due to the presence of both international and local relay suppliers in the region. Among them, major players in the market are Robert Bosch GmbH, Denso Corporation, TE Connectivity Ltd, and Panasonic Corporation.

To meet the consistently growing demand for plug-in relays in automobiles, automotive electronics companies are focusing on manufacturing high-power and reliable relays for automotive applications. For instance, in March 2018, Eberspächer Controls Landau GmbH & Co. KG introduced a new solid-state plug-in power mini relay (12 V / 100 A) for switching electric loads in passenger cars, commercial vehicles, and off-road vehicles.
