The HONGFA HFD5 series represents the industry's smallest fifth-generation signal relay, featuring a compact footprint that is over 40% smaller than the previous HFD4. Designed to integrate into every corner requiring control, this miniature series focuses on enhancing reliability rather than amplifying signals. It achieves significant energy efficiency with coil power consumption as low as 30mW—a reduction of up to 78% compared to its predecessor—while its low operating current of ≤10mA allows it to be driven directly by microprocessors.
