What KOHSHIN does

KOHSHIN Electric Corporation (甲神電機株式会社) is a privately held Japanese manufacturer founded in 1966 and headquartered in Kasaoka, Okayama Prefecture. The company designs, manufactures, and sells current sensors, EMC noise countermeasure components, indicator instruments, and custom embedded devices. Its current sensor portfolio spans four sensing technologies — Hall effect open-loop (HC, HP), closed-loop Hall (HS), digital Delta-Sigma output (HD), and fluxgate/zero-flux (HM, HF) — covering rated currents from 1A to 4000A, with accuracy up to ±300 ppm on fluxgate variants and response times as fast as 0.3 µs. KOHSHIN serves industrial automation (inverters, servo drivers, NC machine tools, UPS, welding equipment), renewable energy (solar PV inverters, fuel cell systems), automotive xEV (EV/HEV/PHEV inverters and battery management), and medical imaging (MRI) OEMs, with an additional OEM manufacturing relationship with Mitsubishi Electric for indicator instruments.

The company operates a distributor-mediated sales model: customers contact KOHSHIN directly via email or phone, after which KOHSHIN introduces an authorized distributor based on the application, with sample units and quote-based pricing standard. Custom and full-custom sensor development is offered directly, with lead times and tooling costs negotiated case by case. KOHSHIN maintains ISO 9001 and ISO 14001 certifications, RoHS and China RoHS compliance, and is preparing IATF 16949 certification for automotive qualification. The company operates domestic and overseas production facilities beyond its Okayama headquarters and runs active recruitment for both new graduates and experienced engineers. Manufacturing is the dominant value driver, with product differentiation anchored in sensing accuracy, temperature stability, and customization rather than software or AI capabilities.
