USED MITSUBISHI SD-Q12

The Mitsubishi Electric SD-Q12 is a high-sensitivity DC interface magnetic contactor from the SD-Q Series, designed for compact, high-performance DC operation. It features a 24VDC coil that can be directly driven by transistor (PLC) outputs at 24VDC / 0.1A, eliminating the need for an intermediate interface relay. The SD-Q12 is rated for 20A open heat dissipation with a standard 1NO+1NC auxiliary contact configuration and 3 main poles, and is suitable for motor control, heater switching, dynamic brake circuits, and circuit interruption applications. The unit is IP20 rated and constructed from flame-retardant glass-fiber reinforced thermoplastic (UL94), with finger-safe terminal covers and direct thermal relay mounting without an adapter.
