HFD2-005-S-D Subminiature Signal Relay 5VDC DPDT Sensitive PCB Relay

• The HFD2-005-S-D relay from Hongfa is a compact subminiature signal relay designed for precision switching applications in telecommunications, instrumentation, embedded electronics, and industrial control systems. Its sensitive coil design and compact PCB footprint make it ideal for high-density electronic assemblies requiring dependable low-power switching performance.
• This relay features a Form 2C (DPDT / double pole double throw) contact configuration, allowing simultaneous switching of two independent circuits. The single-side stable operation provides reliable switching performance for signal routing, interface control, and low-current load applications.
• Equipped with a sensitive 5VDC coil and 167 resistance, the relay operates with low coil power consumption of approximately 150mW, making it suitable for energy-efficient electronic systems and direct control from logic or microcontroller circuits.
• The HFD2-005-S-D supports switching currents up to 3A at 30VDC, 2A at 30VDC, and 1A at 125VAC, offering versatility across both AC and DC switching environments. Its Ag-AuAg8 contact material ensures excellent conductivity, low contact resistance, and long operational life, particularly in signal-level applications.
• The compact vertical PCB mounting design and sealed construction improve reliability while conserving valuable board space in compact electronic products.
