The DS1E-S-DC9V is a high-sensitivity 1 Form C single-side stable relay designed for low-power switching applications with a nominal coil voltage of 9V DC. This relay features a nominal operating power of 200 mW, a coil resistance of 405 O, and a nominal operating current of 22.2 mA, making it suitable for sensitive control circuits. The relay exhibits a pick-up voltage of 80% or less of nominal voltage and a drop-out voltage of 10% or more of nominal voltage, with a maximum applied voltage rating of 160% of nominal voltage at 1 Form C configuration. The DIL terminal array enables direct use with IC sockets, and the relay is commonly applied in telecommunications equipment, measuring devices, office equipment, computers, and industrial control systems where reliable low-power switching is required.
