Handle demanding electrical loads with confidence using the SANYOU SFK-112DM 12V Relay. This high-power electromagnetic relay is engineered for heavy-duty applications, boasting a massive 20A switching capacity at 250VAC. Its unique hybrid terminal design features standard PCB pins for secure board mounting alongside top-facing quick-connect male tabs for high-current wiring.
20A Heavy-Duty Switching: Rated for high-current applications up to 20A at 250VAC, making it ideal for power-hungry appliances and industrial tools.
12V DC Precision Coil: Optimized for stable operation in standard 12V DC control systems.
Hybrid Terminal Design: Combines 4-pin PCB through-hole mounting with two top-side quick-connect terminals to ensure safe, low-resistance connections for high-amperage lines.
Robust Construction: Built with high-quality flame-retardant materials to withstand the thermal demands of continuous high-current switching.
Global Safety Compliance: Fully recognized by international safety standards including UL, CQC, VDE, and TUV, ensuring reliability in exported goods and professional projects.
The SANYOU SFK-112DM Relay is a critical component for:
High-Power Home Appliances: Widely used in air conditioners, heaters, washing machines, and microwave ovens.
Industrial Controls: Ideal for motor starters, pump controls, and high-wattage lighting arrays.
Automotive Electronics: Suitable for 12V auxiliary power systems, cooling fans, and high-intensity discharge (HID) lighting.
Power Supplies & UPS: Providing robust switching for battery backup systems and large-scale power distribution units.
Coil Voltage: 12V DC.
Switching Capacity: 20A 250VAC.
Can the PCB pins alone handle 20A?
For maximum safety and performance at full 20A loads, it is recommended to use the top quick-connect terminals for your high-power lines. The PCB pins are primarily for the 12V coil control and lighter signal paths.
Is this relay "Normally Open" or "Normally Closed"?
The SFK-112DM is a Normally Open (NO) relay. This means the high-power circuit remains open (off) until 12V is applied to the coil.
Can I mount this on a standard prototype board?
Yes, the bottom pins are designed for standard PCB spacing. However, ensure your PCB copper traces are wide enough (or reinforced with solder/wire) to handle the amperage you intend to switch.
