HFD42-12-L13 Signal Subminiature Mini Sealed 1-Coil Latching Relay 12VDC

The HFD42-12-L13 is a compact subminiature sealed latching signal relay designed for efficient, low-power switching in space-constrained electronic systems. Built with a Form 2C (DPDT / 2c/o) contact configuration, it provides reliable dual-circuit control while maintaining excellent electrical stability and durability.

This model uses a 12VDC coil with 1440 coil resistance and a single-coil latching mechanism, meaning it consumes power only during switching states, making it highly energy-efficient for battery-powered or power-sensitive applications.

Its gold flash contacts ensure low contact resistance, stable signal integrity, and long operational life. The relay supports up to 1A at 30VDC and 0.5A at 125VAC (250VAC max), making it suitable for both AC and DC signal-level switching. The sealed construction provides protection against dust and contamination, improving reliability in harsh environments.
