描述

AZ428-56-4LUS is a miniature four-pole general-purpose relay designed for reliable switching applications. It features a 48 VDC nominal coil voltage with a maximum continuous rating of 70 VDC, a coil resistance of 2,500 ohms (±10%), and must-operate voltage of 36 VDC. The relay employs single crossbar fine silver/gold plated contacts with a maximum switched load of 100 W or 350 VA and maximum current rating of 2 Amps at 150 VDC or 300 VAC. The relay offers exceptional mechanical life expectancy of 500 million operations and electrical performance with contact-to-contact capacitance of 2 pF, contact bounce of 3 ms at nominal coil voltage, and dielectric strength of 1500 Vrms between contact and coil. Operating temperature range extends from -55°C to 80°C, with polycarbonate enclosure, tin-plated copper alloy PC terminals, and a weight of 23 to 35 grams. This relay is ideal for industrial control, telecommunications, and instrumentation applications requiring compact, high-reliability switching in harsh environments.
