What I-PEX does

I-PEX Inc. is a Kyoto-headquartered precision manufacturer specializing in very small, high-quality electronic connectors and related micro-electro-mechanical systems. Founded in 1963 as Dai-ichi Seiko Co., Ltd. and rebranded to I-PEX Inc. in 2020, the company operates 39 sites across 12 countries with more than 5,000 employees. Its core portfolio spans RF connectors, micro-coaxial and twinaxial connectors, board-to-board connectors (NOVASTACK series), FPC/FFC connectors (CABLINE series), I/O connectors, wire-to-board and card edge connectors, plus complementary precision-molded parts, transfer-molded automotive ECU encapsulation, MEMS foundry services (KRYSTAL Wafer piezoelectric technology), sensor products (Smart Cloth, noseStick BB), and RENERATH stationary battery storage systems built on repurposed EV batteries. The proprietary stack includes ZenShield EMC shielding, χ-Ni microcrystalline plating, resin plating, and Pt/ZrO₂ buffer layer piezoelectric thin-film technology.

I-PEX serves automotive OEMs and Tier 1 suppliers (headlamp, ECU, power electronics, EV battery system connectors), consumer electronics manufacturers (smartphones, laptops, tablets, AR/VR, wearables), semiconductor and fabless MEMS customers, data center equipment makers, medical device manufacturers, telecom infrastructure providers, and collaborative robot makers. The company holds IATF 16949:2016, ISO 9001, ISO 14001, and ISO 45001 certifications at its Philippines facility, with R&D centers in Kyoto and Tokyo and manufacturing in Japan, the Philippines, the United States (Auburn, Alabama), Singapore, Malaysia, Indonesia, Thailand, and China.

The business model is hardware-led with a direct enterprise sales motion: quote-based B2B pricing mediated by regional sales engineers and sample request workflows across Japan, the US, China, Taiwan, Korea, Singapore, France, and now India, complemented by DigiKey and Thomasnet channels for prototype and SMB volumes, and a contract manufacturing/services arm for custom tooling and automation. I-PEX transitioned from a Tokyo Stock Exchange Prime Market listing (Code: 6640) to private ownership through a March 2025 management buyout and now operates under President Reiji Konishi, with the HQ relocated in November 2025 to Shijo Karasuma in central Kyoto.
