HFD42-2.4-3 Signal Subminiature Mini Sealed Relay 2.4VDC DPDT

The HFD42-2.4-3 is a compact subminiature sealed signal relay designed for reliable low-voltage switching in dense electronic assemblies. With a Form 2C (DPDT / 2c/o) contact configuration, it provides precise dual-circuit control while maintaining a very small footprint for PCB integration.

This relay operates with a 2.4VDC coil and a 41 coil resistance, making it a low-voltage, high-current coil design suited for efficient actuation in compact systems. Its gold flash contacts ensure excellent conductivity, low contact resistance, and long operational life, supporting stable signal performance across repeated switching cycles.

It is rated for 1A at 30VDC and 0.5A at 125VAC (250VAC max), making it suitable for both AC and DC signal-level applications. The sealed construction helps protect internal components from dust and environmental contamination, improving long-term reliability in industrial and embedded environments.
