Omron PCB Power Relay 5V DC Coil, 10A SPDT, Solder Terminal G2R-1 DC5

The Omron G2R-1 DC5 PCB Power Relay is an advanced, general-purpose relay engineered for dependable control and switching in a wide range of electronic and industrial applications. It features a robust 5V DC coil, enabling efficient interfacing with low-voltage logic and microcontroller systems. The G2R-1 DC5 is designed to handle a maximum switching current of 10A, making it suitable for high-load operations in control panels, automation systems, power management, and safety circuits.

This relay is equipped with a single-pole double-throw (SPDT) contact configuration, providing flexible switching possibilities between circuits. The use of silver alloy for contacts ensures superior conductivity, minimal contact resistance of 30 mΩ, and enhanced longevity, even under frequent switching cycles. Its solder-type terminals are optimally designed for secure, reliable mounting directly onto PCBs, streamlining the integration process in both new and existing assemblies.

The relay's compact enclosure measures 29 mm in length, 13 mm in width, and 25.5 mm in height, supporting installations where board space is at a premium. It operates reliably within a wide ambient temperature range from -40°C to 70°C, making it a resilient choice for both indoor and outdoor applications where environmental conditions may fluctuate.

Integrated design elements include a high dielectric strength of 5000 V between coil and contacts and a surge resistance of up to 10,000 V, significantly improving safety and reliability. The product’s robust mechanical structure accommodates standard vibration and shock resistance requirements, with a weight of approximately 17 grams for ease of assembly and reduced board stress. The RoHS-compliant build ensures the relay meets modern environmental standards for electronics manufacturing.

Typical applications for the Omron G2R-1 DC5 include industrial automation controllers, HVAC systems, process control instrumentation, alarm/monitoring devices, power supplies, and commercial electronics requiring durable high-current switching. Its consistent performance in demanding conditions supports both original equipment manufacturers and MRO professionals.

Engineers benefit from features such as solder terminals for quick integration, precise coil resistance of 47 Ω, fast operate (15 ms max) and release (5 ms max) times, and proofed endurance against mechanical and electrical stress. The combination of safety, performance, and compact size makes the G2R-1 DC5 an essential choice for industrial, commercial, and laboratory circuit designers seeking high-reliability relay solutions.
