The AZ2150-1A-18DE is a miniature power relay in a sealed enclosure, designed for high-current applications. It operates with a nominal coil voltage of 18 VDC, has a coil resistance of 380 Ohms, and a must-operate voltage of 13.5 VDC. This relay's 1 Form A (SPST-NO) silver cadmium oxide contacts are rated for a maximum switching current of 40A and a maximum voltage of 300 VAC or 30 VDC. Key performance characteristics include a dielectric strength of 2500 Vrms between the contact and coil, a mechanical life expectancy of 10 million operations, and a Class B operating temperature range of -55°C to 100°C. The sealed construction makes it suitable for automatic wave soldering and immersion cleaning, ideal for use in industrial controls, HVAC systems, and refrigeration equipment compliant with UL 508 and UL 873 standards.
