The global circular connector market is estimated to grow at a CAGR of 5.82% during the forecast period.

A circular connector is a cylindrical electrical connector with multiple pins designed to enable the supply of power, data transmission, or electrical signal transmission to various devices. The circular connector serves a wide range of industries, including aerospace & defense, transportation, electrical & electronics, telecommunications, and various other sectors. The increasing demand for reliable and efficient electrical connections emerges as a prominent driver fuelling the growth of the circular connector industry.

Rise in electronic production boosts the circular connector market growth.

Circular connectors are extensively used in electronic products due to their versatility, reliability, and compatibility with a wide range of electronic devices and systems. They provide a secure and robust connection for power transmission, data communication, and signal transmission, ensuring efficient and uninterrupted operation. As electronic production continues to increase, due to rising consumer demand for electronic devices, the need for circular connectors becomes even more crucial to meet the expanding requirements of electronic production. According to the U.S. Bureau of Labor Statistics, in 2021, computer and electronic production in the U.S. witnessed a notable growth of 6% compared to the previous year.

The emerging transportation sector drives the circular connector industry expansion.

Circular connectors have extensive usage in the transportation industry due to their durability, reliability, and ability to withstand harsh environmental conditions. They are commonly employed in automotive applications, including electric vehicles (EVs), where they facilitate power transmission, data communication, and control systems.  The rising demand for efficient and sustainable transportation solutions is driving the adoption of circular connectors in the transportation sector. According to the Bureau of Transportation Statistics, in 2021, electric vehicle sales in the United States experienced a remarkable surge, with a notable increase of 104.3% compared to the previous year.

Emerging data centres drive circular connector market growth.

Data centers require a robust and reliable infrastructure to handle the ever-increasing volume of data processing and storage. Circular connectors offer high-performance electrical connections, ensuring efficient power transmission, data transfer, and signal integrity within the complex network of servers, switches, and storage systems. The demand for data centers continues to rise as businesses and organizations seek to store, manage, and analyze vast amounts of data, leading to increased adoption of circular connectors in these critical facilities. According to International Energy Agency, the workload of data centers experienced a remarkable surge, reaching 650 million in 2021, which represents a staggering 260% increase when compared to the workload in 2015.

Asia-Pacific is estimated to dominate the market.

Asia-Pacific region is expected to hold a significant share of the circular connector market due to the region's booming electronic production which has fuelled the demand for circular connectors. For instance, according to the Ministry of Economic Affairs (MOEA), in 2022, Taiwan's computer manufacturing sector output reached NT$321.5 billion. Additionally, the Asia Pacific's prominence in the circular connector market is bolstered by the government's initiatives for the adoption of electric vehicles (EVs). For instance, in India, electric vehicles are included in the (PLI) scheme for Automobile and Auto Components, approved on 15th September 2021, with a budget of Rs. 25,938 crore for five years.

The need for customizations restrains the circular connector market growth.

Customization is a significant factor restraining the expansion of the circular connector market size. Due to specific application requirements, such as unique pin layouts, environmental sealing, or specialized materials, circular connectors often need to be customized. However, this customization process can lead to increased costs, longer lead times, and added complexity, which may make them less attractive to certain customers. While standardization efforts have been made to mitigate this challenge, the need for customization still poses a significant hurdle in expanding the adoption of circular connectors.

Key Developments

  • March 2022: CUI Devices' Interconnect Group broadened its range of connectors by introducing a new line of circular connectors, enhancing its overall product portfolio. The newly added CDM12 family comprises M12 connector types, providing a variety of options including male or female versions and contact positions ranging from 3 to 12 pins. These connectors are designed with A-coding and support 1 Gbit Ethernet, making them suitable for industrial and factory automation applications. Additionally, all M12 connector models in the CDM12 family carry IP67 ratings, ensuring their durability and protection against harsh environments.
  • October 2021: A collaboration between STMicroelectronics (ST) and Rosenberger has led to the development of an innovative contactless connector technology intending to reduce the number of wires in connectors. This novel high-speed contactless connector has the potential to address connector-related failures commonly encountered in electromechanical applications, offering a promising solution in the industry.
