The SF2D-DC12V is a flat-type double-contact safety relay manufactured by Panasonic with a nominal coil voltage of 12V DC and 2 Form A and 2 Form B contact arrangement. It features forced-operation contacts where N.O. and N.C. side contacts are mechanically linked through a card so that if one contact welds, the other maintains a minimum 0.5 mm contact gap, ensuring continued safe operation. The relay achieves high contact reliability through Au-flashed AgSnO2 contact material, a separated chamber structure that prevents short circuits between contact sets, and a high-efficiency polarized magnetic circuit that enables 500 mW nominal operating power. With a maximum switching capacity of 6A at 250V AC or 30V DC, breakdown voltage of 2,500 Vrms between contact and coil, and compliance with UL, CSA, TÜV, and SEV safety standards, this relay is ideal for industrial equipment such as presses, machine tools, elevators, and conveyor systems where safety and reliability are critical.
