HF7520-005-HSPQ High Power Sealed PCB Relay 5VDC SPST-NO 16A Terminal Relay

The HF7520-005-HSPQ relay from Hongfa is a high-power, capacity-grade sealed relay designed for demanding switching applications where both high current handling and robust mechanical installation are required. It is widely used in industrial control systems, appliances, HVAC equipment, power distribution modules, and high-load PCB assemblies.

This model features a Form 1A (SPST-NO) contact configuration, providing reliable normally open switching for power loads. Its 5VDC coil with 125 resistance allows efficient low-voltage operation suitable for microcontroller-driven circuits, embedded control systems, and logic-level automation designs.

The HF7520-005-HSPQ supports switching capabilities of up to 16A at 250VAC and 10A at 30VDC, making it suitable for motors, compressors, heaters, lighting circuits, and general-purpose high-current loads. Its sealed construction protects the internal contact system from dust, flux contamination, and environmental exposure, improving long-term reliability.

A key feature of this relay is its horizontal PCB mounting design combined with 6.3mm vertical Fast-On (quick-connect) terminals. This hybrid configuration allows both PCB integration and high-current field wiring, making it ideal for power modules and industrial control boards where durability and serviceability are important.
