Connectors are electromechanical components that establish secure, reliable links between devices to enable the transmission of signals, power, and data. Though individually small and often overlooked, they underpin the function of everything from smartphones and data centres to electric vehicles and aerospace systems. As electronics grow more complex, miniaturised, and networked, demand for higher-performance connector solutions is intensifying across virtually every sector.
Automotive Sector Emerges as the Dominant End-Use Vertical
Among end-use verticals, the automotive segment is expected to account for the highest connector market share over the forecast period. The proliferation of electronic systems within modern vehicles is a central driver: advanced driver assistance systems (ADAS), in-vehicle infotainment, electrified powertrains, and an expanding array of sensors all depend on reliable, high-integrity connector solutions.
The transition toward electric vehicles is accelerating this trend. EV architectures require connectors capable of handling higher voltages and currents than conventional vehicles, while also meeting stringent standards for safety, thermal performance, and vibration resistance. In July 2023, ABB announced the launch of what it described as the world’s first full range of hinged high-voltage connector backshells designed for heavy-duty electric vehicles, with the Harnessflex EVO series targeting improved cable-to-connector stability in high-voltage applications.
Autonomous and semi-autonomous vehicle development is adding further complexity to connector requirements, as the sensor arrays and redundant communication systems required for these platforms demand solutions that combine high data throughput with exceptional reliability.
PCB Connectors Lead by Product Type; Copper Dominates Materials
By product category, PCB connectors represented the largest segment, with revenues estimated at approximately $22.1 billion in 2023. Growth in the broader electronics industry, advances in semiconductor technology, and rising demand for automotive electronics all contribute to PCB connector demand. Other significant product categories include I/O connectors, circular connectors, fiber optic connectors, and RF coaxial connectors.
On the materials side, copper accounted for the largest share at 32.8% in 2023. Copper’s outstanding electrical conductivity makes it the material of choice for applications where rapid data transfer is essential, including telecommunications infrastructure, data centres, and 5G networks. Newer materials including titanium, gold, nickel, and brass are gaining ground in specialist applications, with the “other materials” segment projected to record the highest CAGR through 2032 as more diverse connectivity requirements emerge across industries.
Telecom Expansion and 5G Infrastructure Drive Data Connector Demand
The telecommunications sector remains one of the largest and most dynamic end markets for connectors. Routers, switches, modems, and fiber optic transceivers all rely on precision connectors to maintain signal integrity across increasingly high-bandwidth networks. The global rollout of 5G infrastructure is significantly elevating performance requirements, with connectors now needing to support higher frequencies, lower latency, and greater data density than previous-generation networks required.
The convergence of 5G and IoT is creating compounding demand. As more devices connect to networks — from industrial sensors to consumer wearables — the volume of connector-equipped hardware entering the market expands accordingly. Analysts identify this combination as one of the more significant long-term structural opportunities for connector manufacturers.
In March 2023, Hirose Electric launched its IT14 Series board-to-board connector, supporting transmission speeds of up to 112Gbps PAM4 — a specification that reflects the data throughput requirements now emerging in server, telecommunications, and data centre applications.
Asia-Pacific Holds the Largest Regional Share
Geographically, Asia-Pacific accounted for the largest regional share of the connector market in 2023. Rapid industrialisation in China, India, and Southeast Asia has increased demand for electronic devices and infrastructure across manufacturing, automotive, and telecommunications sectors. The region also serves as the primary global hub for the production and assembly of consumer electronics, automotive components, and telecommunications equipment — all industries that consume connectors at scale.
Supportive government policies, investment in technology infrastructure, and a growing consumer population are expected to sustain Asia-Pacific’s leading position through 2032. The region is also anticipated to record among the highest CAGRs, driven by continued expansion in automotive electronics and the buildout of 5G and data centre infrastructure across emerging markets.
North America and Europe remain significant markets, with demand sustained by aerospace and defence procurement, industrial automation, and the ongoing transition to electric vehicles among established automotive manufacturers.
