HFD2-005-S-L2-D Subminiature Signal Relay 5VDC DPDT Double Latching Relay

Description:
- The HFD2-005-S-L2-D relay from Hongfa is a high-performance subminiature signal relay designed for compact electronic systems requiring low power consumption, dual-circuit switching, and latching functionality. Its miniature footprint and efficient double coil latching mechanism make it ideal for telecommunications, instrumentation, automation, and battery-powered devices.
- This relay features a Form 2C (DPDT / double pole double throw) contact configuration, allowing simultaneous switching of two independent circuits. The double coil latching design enables the relay to maintain its contact position without continuous coil power, reducing overall energy consumption and improving efficiency in portable or low-power systems.
- Equipped with a sensitive 5VDC coil and 167 coil resistance, the relay operates with approximately 150mW coil power, ensuring responsive and efficient switching. The high-quality Ag-AuAg8 contact material delivers excellent conductivity, low contact resistance, and dependable long-term signal performance.
- The HFD2-005-S-L2-D supports switching ratings up to 3A at 30VDC, 2A at 30VDC, and 1A at 125VAC, making it suitable for both signal-level and light-load switching applications. Its compact vertical PCB mounting configuration allows easy integration into high-density electronic assemblies.
