LONDON, 2025 — Claritas Intelligence has published its global market report on screw-in data connectors, sizing the market at USD 2.9 billion in 2025 and projecting a base-case expansion to USD 4.8 billion by 2033, equivalent to a 6.4% CAGR over the 2026–2033 forecast period.
The dominant demand signal is industrial automation, which commands roughly 34% of 2025 revenue. IEC 61076-compliant M12 and M8 screw-lock formats are systematically embedded at sensors, drives, and PLCs running PROFIBUS, PROFINET, and EtherCAT field-bus topologies. Machine-builder OEM design cycles run 3–7 years, meaning socket commitments made today lock in connector specifications well into the next decade. Alongside factory automation, defense and aerospace procurement — spanning MIL-DTL-38999 and MIL-DTL-26482 threaded-coupling formats — sustains elevated average selling prices, with MIL-spec units carrying ASPs of USD 25–300 per connector versus USD 1–5 for commercial M12 grades. NATO burden-sharing commitments, US DoD modernization programs, and AUKUS-related electronics procurement are all sustaining multi-year order pipelines.
The fastest-growing end-use segment, on the report's model, is automotive at an estimated 8.9% CAGR from 2026 to 2033. The driver is structural: 800V SiC inverter platforms, multi-gig IEEE 802.3ch automotive Ethernet, and LiDAR/ADAS sensor chains require IP67/IP69K threaded interconnects rated to AEC-Q200 vibration classes. The global EV production ramp adds millions of BMS wiring harness connector positions per year, each of which represents a discrete screw-retention socket. The report's counter-consensus position on data centers is notable: hyperscale operators' migration to OCP NIC 3.0 and PCIe Gen5/Gen6 blind-mate press-fit connectors is projected to constrain screw-lock demand in that vertical to sub-2% CAGR through 2033, partially offsetting gains from industrial and automotive end markets.
Asia Pacific holds approximately 41% of the 2025 global market and is simultaneously the largest and fastest-growing region. China's mature-node fab build-out and Japan METI-subsidized semiconductor packaging investments both specify ruggedized board-to-board screw-retention connectors at equipment-automation interfaces. The USD 52.7 billion US CHIPS and Science Act and the EUR 43 billion EU Chips Act are directing greenfield 300mm fab construction that requires tens of thousands of M12 SMEMA/GEM connector positions per installation, providing a secondary growth vector for North America and Europe through the forecast horizon.
The competitive landscape is concentrated among a small number of global interconnect specialists. Key suppliers profiled in the report include TE Connectivity plc, Amphenol Corporation, Molex LLC (Koch Industries), Phoenix Contact GmbH & Co. KG, Hirose Electric Co., Ltd., Samtec, Inc., Switchcraft Inc. (Conxall), Japan Aviation Electronics Industry Ltd. (JAE), Rosenberger Hochfrequenztechnik GmbH & Co. KG, Huber+Suhner AG, Harting Technology Group, and LEMO SA. TE Connectivity reported USD 17.26 billion in total group revenue in FY2025, with industrial and harsh-environment connectivity among its fastest-growing reported verticals. Amphenol posted USD 23.09 billion in group revenue in FY2025, up 52% from USD 15.22 billion in FY2024, partly reflecting the Andrew/GTEC acquisition and surging data-center orders.
"Industrial automation and electrified automotive architectures are doing the heavy lifting in this market. The risk that most forecasters underweight is the accelerating press-fit substitution in hyperscale data centers; our view is that the industrial and EV verticals will more than compensate, but the data-center tailwind many models assume is largely illusory." — Saurabh Shetty, Senior Analyst, Claritas Intelligence
