Positioned as an engineering-driven B2B supplier, ATO Relays eliminates typical procurement bottlenecks by combining custom relay development with low MOQs, rapid prototyping, and direct factory pricing. Over fifteen years of dedicated relay manufacturing enables ATO to adapt quickly to client-specific electrical requirements. Powered by automated assembly equipment, ISO-certified quality protocols, and exhaustive in-house electrical life testing, the company guarantees consistent lot-to-lot reliability to keep client manufacturing schedules on track.
ATO’s diverse circuit control catalog focuses on minimizing downtime while improving operational energy efficiency. The company’s Solid State Relay (SSR) series handles AC and DC loads up to 350A, incorporating optical signal isolation to protect control logic from high-voltage spikes and transient electrical noise. Designed with heavy-duty heat dissipation surfaces and compact mounting bases, these solid-state units provide arc-free switching and extended maintenance-free service in vibration-heavy industrial environments.
Complementing its semiconductor switching devices, ATO manufactures industrial Electromagnetic Relays in DPDT, 3PDT, and 4PDT designs, alongside ultra-thin interface modules engineered for PLC panels. Featuring low-power coil designs and silver-alloy contact sets to minimize electrical resistance, these relays are enclosed in clear protective shells for quick status verification without opening safety covers during active operation.
From custom pin configurations and specialized terminal wiring to custom coil voltages, ATO offers true OEM/ODM versatility backed by extensive warehouse inventory for fast same-day fulfillment. ATO Relays supports system integrators, HVAC machinery manufacturers, and industrial panel builders throughout Europe, North America, and East Asia with factory-direct responsiveness and full warranty protection.
