G5NB-1A-E DC12
Category
The Omron G5NB-1A-E DC12 is a 12V-powered SPST-NO relay designed for industrial automation applications, offering 5A switching capacity at 250V AC/30V DC with 10ms response times. It features cadmium-free silver alloy contacts and operates reliably within -40°C to +85°C. Ideal for control systems in manufacturing, renewable energy, and medical devices, its compact size and ROHS compliance make it suitable for space-constrained environments, though cost and frequency limitations should be considered in high-performance scenarios.
