The SRI(T72) Relay embodies the core value of a "professional-grade relay" with its robust performance: It innovatively adopts a low-loss contact structure with a contact resistance ≤100mΩ, coupled with 10⁵ electrical cycles and 10⁷ mechanical cycles, ensuring conduction stability under long-term, high-frequency operation; a wide nominal voltage range of 5-36VDC and multiple power consumption options of 0.54W/0.72W/0.62W adaptable to diverse circuit designs; and a safety configuration with a 2000VAC coil-contact withstand voltage and a 100MΩ high insulation resistance, creating a double protection barrier. Leveraging Songle's 27 years of relay R&D experience, the product achieves an innovative balance of "high load capacity + low power consumption" in its core parameters. The PCB terminal design simplifies the installation process, and the upgraded sealing protection can cope with complex industrial environments. From raw material selection to finished product testing, the entire process of quality control is streamlined, and global professional after-sales service is provided. With verifiable performance data, authoritative certifications, and brand heritage,SRI(T72) Relay has become the first choice for enterprise customers who seek reliability and cost-effectiveness.
