UD2-5NU-L – NEC TOKIN

The UD2-5NU-L is a miniature, dual-pole, double-throw (DPDT) electromechanical relay manufactured by NEC TOKIN. This general-purpose relay is designed for low-signal switching applications, featuring a contact rating of 1 Ampere at a specified voltage, typically 30VDC or 125VAC, depending on the load type and application circuit. The coil is rated for 5VDC nominal voltage, requiring a defined pull-in current to actuate the armature and switch the contacts. The relay exhibits a low profile for high-density PCB mounting and is commonly used in telecommunications, industrial control, and consumer electronics for signal routing, isolation, and interface functions. Its DPDT configuration allows for versatile switching of two independent circuits simultaneously, offering increased flexibility in circuit design.
