Yueqing Huilong’s DC relay 12V is designed for low-voltage direct current systems, providing efficient switching in battery-powered and industrial control setups. This relay features a compact design with a hermetically sealed housing, protecting internal components from dust and moisture. The 12V DC coil consumes only 0.5W power, enabling energy-efficient operation, while gold-plated contacts (15A/30V DC) ensure low resistance and reliable signal transmission. It incorporates an anti-reverse diode to protect against voltage spikes, making it suitable for inductive loads like solenoids and motors. The relay supports both through-hole and surface-mount installation, adapting to different PCB designs, and offers a mechanical life of 10 million cycles, ensuring durability in automotive electronics, renewable energy systems, and portable devices.
