The micro relay from Yueqing Huilong is a miniature switching device designed for high - density electronic applications. Measuring 10mm x 8mm x 5mm, this relay features a surface - mount package (SOP - 8) compatible with microelectronics and compact circuits. The relay’s coil operates at low power (0.15W), making it suitable for battery - operated devices and energy - efficient systems. Its gold - plated contacts (0.5A/24V DC) provide excellent signal integrity, while the hermetically sealed construction prevents contamination from dust and moisture. The micro relay supports a wide operating temperature range (- 40℃ to + 105℃), ensuring reliability in harsh environments. Ideal for use in smartphones, wearable devices, and medical sensors, this relay offers a mechanical life of 50 million cycles, balancing miniaturization with durability for high - volume applications.
