Engineered to streamline supply chain management for global automation and equipment manufacturers, ATO Relays delivers high-performance circuit control through direct OEM/ODM customization, low MOQs, competitive direct factory pricing, and rapid order processing. Backed by more than fifteen years of specialized relay manufacturing experience, ATO operates ISO-certified production facilities equipped with automated assembly machinery, expert in-house engineering, and comprehensive lifecycle endurance testing to ensure consistent lot-to-lot reliability.

The company's product portfolio spans over thirty distinct series focused on extending machine service life and optimizing cabinet space. ATO offers single-phase and 3-phase Solid State Relays (SSRs) managing load currents from 10A to 350A (3-32V DC input to 24-480V AC output). Built with integrated aluminum heat sinks and vibration-resistant DIN rail mounting clips, these semiconductor switches provide maintenance-free, spark-free, and high-speed silent switching in high-duty cycle environments.

For versatile logic and power control, ATO manufactures industrial Electromagnetic Relays in DPDT, 11-pin 3PDT with high-conductivity silver-alloy contacts, and 4PDT arrangements, alongside ultra-compact 24V DC SPDT PLC interface modules. Operating smoothly across temperatures from -25°C to 55°C, these relays feature clear insulated housing for instant visual status checks while ensuring high electrical safety inside dense control panels.

By combining tailored parameter modifications—including custom coil voltages, contact layouts, and terminal configurations—with rapid prototyping and millions of standard components maintained in stock for same-day dispatch, ATO shortens product development cycles. Certified to international safety standards, ATO Relays provides machine builders, panel integrators, and commercial distributors across North America, Europe, and the Asia-Pacific region with trusted quality and dedicated technical support.
