The HF7FD-012-1HS relay from Hongfa is a subminiature high-power PCB relay designed for compact yet high-current switching applications. It is widely used in industrial control systems, home appliances, HVAC equipment, power modules, and embedded electronics where space is limited but reliable load switching is essential.

This relay features a Form 1A (SPST-NO) contact configuration, providing normally open switching suitable for direct load control. Its 12VDC coil with 400 resistance ensures efficient activation and stable performance in standard control circuits, including microcontroller-driven systems and industrial automation boards.

With a strong electrical rating of 16A at 250VAC, the HF7FD-012-1HS is suitable for switching motors, heaters, compressors, lighting systems, and other high-load AC applications. Despite its subminiature size, it delivers industrial-grade switching performance with long operational life.

The relay is designed for PCB mounting, allowing easy integration into compact electronic assemblies. Its construction supports high-current pathways while maintaining thermal stability and mechanical durability under continuous load conditions.
