The BTA2G Series Latching Relays are high-performance electromagnetic relay devices designed for reliable bistable switching in industrial automation, smart energy systems, and control panels. Featuring magnetic latching technology, these relays maintain their contact position without continuous coil power, reducing energy consumption while ensuring stable and long-lasting operation.
Key Features
Magnetic Latching Design – Maintains ON/OFF state without continuous power, ideal for energy-saving applications.
High Switching Capacity – Supports heavy resistive and motor loads for industrial and appliance control.
Flexible Configuration Options – Multiple contact forms (1C / 2C), shell types, coil voltages, and terminal styles available.
Long Service Life – Durable AgSnO₂ contacts ensure reliable switching over millions of operations.
Compact Plug-In Design – Easy installation and maintenance for PLC panels and automation equipment.
