AZ421-70-1LUS is a miniature general purpose 4-pole (4PDT) DC relay designed for reliable switching applications. It features a 24 VDC nominal coil voltage with 700 ohms ±10% coil resistance and a must operate voltage of 18.0 VDC, with maximum continuous voltage of 37 VDC. The relay utilizes single crossbar fine silver/gold plated contacts (1LUS) with maximum power rating of 100 W or 350 VA and maximum current of 2 Amps. Key specifications include mechanical life expectancy of 500 million operations, contact resistance less than 50 milliohms, dielectric strength of 1500 Vrms contact to coil, and operating temperature range of -55°C to 80°C. The unsealed plug-in/solder terminal design with polycarbonate enclosure makes it suitable for industrial control, instrumentation, and general switching applications requiring high reliability.
