HFD4-2.4-SR Signal Subminiature Mini Seal Surface Mount Relay 2.4VDC DPDT

Upgrade your compact electronic designs with the HFD4-2.4-SR, a subminiature surface-mount (SMD) sealed signal relay from Hongfa. Designed for high reliability in small form factors, this relay offers dual-pole, double-throw switching (Form 2C / 2c/o) for precise control in tight PCB layouts.

With a 2.4VDC coil and 41 coil resistance, the HFD4-2.4-SR operates efficiently, supporting a maximum switching current of 2A at 30VDC and 0.5A at 125VAC. Its gold flash contacts provide excellent conductivity, low contact resistance, and long operational life, ensuring consistent performance in both AC and DC applications.

The sealed SMD construction protects against dust and environmental contaminants, making it ideal for surface-mount PCB integration in industrial, telecommunications, and control systems. Its compact footprint allows for efficient space utilization without compromising reliability.
