HY1-5V is a non-polarized single-pole double-throw (1 Form C) relay designed for high sensitivity applications with a nominal operating power of 150 mW. It features a 5V DC nominal coil voltage with 30 mA nominal operating current and 166O coil resistance. The relay utilizes gold-clad twin contacts (Ag + Au clad) for high contact reliability and offers a nominal switching capacity of 1 A at 30V DC resistive load. With sealed construction, RoHS compliance, and compact dimensions of approximately 12 mm × 7.4 mm × 10.1 mm, this relay is well-suited for telecommunications equipment, security systems, test and measurement equipment, and consumer electronics applications.
