Frequently Asked Questions

How do I select the right Hongfa power relay for my appliance application?

Selecting the right Hongfa power relay involves several considerations: 1) Contact Rating - choose a relay with contact rating at least 20% higher than your load current

for resistive loads use the rated current, for inductive loads apply higher derating, 2) Coil Voltage - match the relay coil voltage to your control circuit voltage (5VDC, 12VDC, 24VDC, etc.), 3) Contact Configuration - select SPST for simple on/off switching, SPDT for changeover applications, or DPDT for dual circuit control, 4) Mounting Type - choose PCB mount for circuit board installation or panel mount for chassis mounting, 5) Environmental Requirements - consider sealed relays (HF35F) for washability or high-temperature versions for hot environments, 6) Safety Certifications - verify UL, VDE, or TÜV certifications match your market requirements. Our FAE team can assist with selection based on your specific load characteristics and application requirements.

What is the difference between HF3F, HF32F, and HF36F power relay series?

The HF3F, HF32F, and HF36F series are all miniature power relays but optimized for different applications: HF3F is a general-purpose 5A relay with compact 19.2mm size, ideal for space-constrained designs in small appliances

HF32F offers 10A capacity with subminiature footprint, suitable for higher current applications while maintaining compact size

HF36F provides 16A switching capacity with reinforced contact construction for demanding industrial loads. Key differences include: Contact Rating - HF3F: 5A, HF32F: 10A, HF36F: 16A

Dimensions - HF3F: 19.2x15.5mm, HF32F: 20.5x10.5mm, HF36F: 24x18mm

Coil Power - all series offer 400-500mW options

Applications - HF3F for small appliances, HF32F for general purpose, HF36F for industrial equipment. All series share common features like 4000VAC dielectric strength, 10M mechanical life, and global safety certifications.

Choose HF3F for compact 5A applications, HF32F for 10A general purpose, HF36F for 16A industrial loads.
