The NC4-PS is a 4-pole slim power relay manufactured by Panasonic for transistor-driven switching applications. It features a compact profile of 11.2 mm width and 10.9 mm height, enabling high-density mounting on printed circuit boards while maintaining a 5A switching capacity at 250V AC or 30V DC. The relay employs Au-clad AgNi contact material with stable contact pressure via card lift-off contact driver method, ensuring high contact reliability with initial contact resistance not exceeding 50 mO. Available in multiple coil voltage options (3V to 100V DC, 12V to 100V AC), the relay is UL and CSA certified and complies with Japanese Electrical Appliance and Material Control Law. This relay is ideal for information processing, telecommunications equipment, and industrial control systems requiring reliable, compact switching solutions.
