The SF3-DC5V is a flat-type safety relay with a 3 Form A and 1 Form B contact arrangement, designed for industrial safety applications. It features forced operation contacts that maintain a minimum 0.5 mm gap between contact sets if welding occurs, and isolated chambers to prevent short circuits. The relay operates at 5 V DC with a coil current of 100 mA, a resistance of 50 Ω, and a nominal power of 500 mW. It switches up to 6 A at 250 V AC and 30 V DC, with a dielectric strength of 2,500 Vrms between contacts and coil. Certified to UL, CSA, TÜV, and SEV standards, it operates from -40°C to +70°C. The device mounts on a PCB with dimensions of 53.3 mm × 25.0 mm × 16 mm and weighs 38 g.
