HFD17-5-ZH-3N Low Power Sub-Mini Sealed Relay 5VDC SPDT 3A High-Sensitivity

• The HFD17-5-ZH-3N relay from Hongfa is a low-power sub-miniature sealed PCB relay designed for compact electronic systems requiring high sensitivity, low coil drive requirements, and reliable signal switching. It is commonly used in embedded electronics, automation modules, consumer devices, and telecom equipment where 5V logic control is standard.
• This relay uses a Form 1C (SPDT / changeover) contact configuration, enabling switching between two output paths or basic control logic implementation. Its 5VDC sensitive coil with 120 resistance and approximately 200mW power consumption allows it to operate with very low input energy, making it ideal for direct microcontroller or logic-level drive circuits.
• It supports a switching capacity of 3A at 125VAC / 24VDC, suitable for signal-level loads, small motors, relays cascades, and general-purpose PCB switching applications. The sealed construction protects internal contacts from dust, oxidation, and flux contamination, improving long-term reliability and stability.
• The compact 5-pin footprint makes it suitable for space-constrained PCB designs, especially in high-density electronic assemblies.
