SANYOUC SFK-112DM Air Conditioner Power Relay 12VDC 20A 4Pins
The SFK-112DM is a single-pole, normally open (Form A) electromagnetic relay designed for reliable switching of AC loads. It is commonly used in applications requiring interface between low-power control circuits and higher-power devices such as motors, heaters, or lighting. The relay offers a compact design with PCB mounting, making it suitable for embedded control systems, power strips, and appliance control boards.
With a focus on durability and electrical isolation, this relay provides safe and efficient switching for resistive and inductive loads. It features a silver alloy contact for low resistance and stable performance, and is available in several coil voltage options to match various control voltages. The relay is widely used in automation, HVAC, industrial equipment, and home appliances due to its robust construction and compliance with international standards.
