Yueqing Huilong’s 12-volt relay is optimized for low-voltage DC systems, delivering reliable switching in automotive, marine, and portable electronics. This relay features a rugged design with a 12V DC coil and silver-cadmium oxide contacts (20A/12V DC), suitable for handling inductive loads like starters and solenoids. The flame-retardant ABS housing (UL94 V-0) withstands temperatures from -30℃ to +80℃, while the built-in flyback diode suppresses voltage spikes, protecting connected circuits. It supports both plug-in and screw-mount installation, with color-coded terminals for easy wiring. The 12-volt relay offers a mechanical life of 10 million cycles and electrical life of 100,000 cycles, making it ideal for vehicle lighting, battery management, and small-scale industrial controls.
