Established in China as a dedicated high-tech relay developer and manufacturer, ATO Relays provides global equipment builders with reliable, cost-effective circuit control solutions. Operating with over 15 years of industry expertise, ATO bridges the gap between scalable manufacturing and custom electrical design. Supported by dedicated technical teams, ATO provides end-to-end service—from initial schematic adaptation to pre-sales consultation and long-term warranty support.

ATO’s product catalogue includes over thirty distinct series engineered to cover both mechanical and semiconductor control requirements. Their solid-state lineup features single-phase and three-phase SSRs capable of handling load currents from 10A up to 350A, engineered with 3-32V DC control inputs and broad 24-480V AC output windows. Designed for harsh operating environments, these SSRs feature high vibration resistance, optional integrated heat sinks, and DIN rail enclosures for seamless installation in modern control cabinets.

For traditional load isolation and signal conversion, ATO supplies specialized electromagnetic relays available in SPDT, DPDT, 3PDT, and 4PDT formats. Offering standard coil options across 12V, 24V, 110V, and 240V, these units feature silver-alloy contacts, transparent protective shells, and slim DIN-rail interface profiles optimized for PLC automation, sound systems, and industrial machinery. Custom options allow B2B clients to adapt current, voltage, and pin parameters to match specific system architectures.

Maintained by a high-capacity logistics warehouse supporting same-day dispatch on standard units, ATO Relays has built an established export footprint across Western Europe, North America, Southeast Asia, and the Middle East. By combining factory-direct pricing with strict quality testing, ATO remains a trusted partner for OEMs, panel builders, and international industrial distributors.
