Miniature relays are compact devices measuring from 15 to 25 mm in width. They have medium-duty application capabilities, striking the balance between size and performance. Unlike micro relays, miniature relays have coil voltage and contact ratings reaching 30 Amps. Their voltages are compatible with low-voltage logic (5V DC) and industrial control (24V DC) systems. Common types include power miniature relays (SPST/SPDT) and latching variants for memory functions. Their rugged enclosures and plug-in bases make them perfects for robotics, medical devices, and renewable energy inverters while meeting UL 508 and CE standards.
