HFD2-003-S-L2-D Subminiature Signal Relay 3VDC DPDT Double Latching Relay

• The HFD2-003-S-L2-D relay from Hongfa is a compact subminiature signal relay designed for precision switching applications where low power consumption, signal integrity, and memory-retention switching are important. Its double coil latching design allows the relay to maintain its switching state without continuous coil power, making it ideal for battery-powered and energy-efficient electronic systems.
• This relay features a Form 2C (DPDT / double pole double throw) contact arrangement, enabling simultaneous switching of two independent circuits. The latching mechanism uses separate set and reset coils, allowing the relay to remain in its last position even after power is removed, significantly reducing overall power consumption.
• Equipped with a sensitive 3VDC coil and 60 resistance, the relay operates with approximately 150mW coil power, ensuring fast and efficient switching performance. The Ag-AuAg8 contact material provides excellent conductivity, low contact resistance, and enhanced reliability for signal-level and low-current applications.
• With switching ratings up to 3A at 30VDC and 1A at 125VAC, the HFD2-003-S-L2-D is suitable for telecommunications, instrumentation, automation, interface circuits, and portable electronic devices. Its compact vertical PCB-mount package makes it ideal for high-density circuit board layouts.
