HF7520-005-HSTP High Power Sealed PCB Relay 5VDC SPST 16A Industrial Relay

The HF7520-005-HSTP relay from Hongfa is a high-power capacity sealed PCB relay designed for robust switching performance in industrial control systems, appliances, HVAC equipment, power distribution units, and high-load electronic circuits. It combines compact PCB mounting with high-current switching capability and sealed construction for enhanced durability.

This relay uses a Form 1A (SPST-NO) contact configuration, providing reliable normally open switching for power control applications. Its 5VDC coil with 125 resistance allows efficient low-voltage operation, making it suitable for embedded systems, microcontroller-driven circuits, and industrial logic control designs.

The HF7520-005-HSTP supports switching up to 16A at 250VAC and 10A at 30VDC, making it suitable for motors, compressors, heaters, lighting systems, industrial automation loads, and appliance control circuits. Its sealed housing protects internal contacts from dust, flux contamination, and environmental exposure, improving operational lifespan and reliability.

A key feature of this variant is its horizontal PCB-mounted structure designed for compact power modules. It is engineered for stable PCB integration while maintaining high-current performance and long-term mechanical reliability in demanding environments.
