HFD42-3-L13 Signal Subminiature Mini Sealed 1-Coil Latching Relay 3VDC DPDT

The HFD42-3-L13 is a compact subminiature sealed latching signal relay designed for efficient low-power switching in modern electronic systems. Featuring a Form 2C (DPDT / 2c/o) contact configuration, this relay provides reliable dual-circuit switching while maintaining a minimal PCB footprint.

This model uses a 3VDC coil with a 90 coil resistance and a single-coil latching mechanism, allowing the relay to maintain its switching state without continuous power consumption. This makes it an ideal solution for battery-powered, portable, and energy-efficient applications.

Its gold flash contacts ensure excellent conductivity, low contact resistance, and dependable long-term switching performance. The relay supports electrical loads up to 1A at 30VDC and 0.5A at 125VAC (250VAC max), making it suitable for both DC and AC signal switching applications.

The sealed construction protects the internal components from dust and contaminants, improving durability and operational reliability in industrial and embedded electronic environments.
