• The HFD2-012-S-L2-D relay from Hongfa is a compact and energy-efficient subminiature signal relay designed for precision switching applications requiring latching functionality and reliable dual-circuit control. Its small footprint, sensitive coil operation, and low power consumption make it ideal for telecommunications, industrial automation, instrumentation, and embedded electronic systems.
• This relay features a Form 2C (DPDT / double pole double throw) contact configuration, allowing simultaneous switching of two independent circuits. The double coil latching mechanism enables the relay to maintain its switched state without continuous coil power, reducing energy consumption and improving efficiency in battery-powered and low-power devices.
• Equipped with a sensitive 12VDC coil and 960 coil resistance, the relay operates with approximately 150mW coil power for efficient and responsive switching. Its Ag-AuAg8 contact material provides excellent conductivity, low contact resistance, and dependable long-term signal integrity.
• The HFD2-012-S-L2-D supports switching capacities up to 3A at 30VDC, 2A at 30VDC, and 1A at 125VAC, making it suitable for both signal-level and light-load control applications. Its vertical PCB mounting design allows easy integration into compact and high-density electronic assemblies.
