DC coil contactor for 24 V control circuits
The Mitsubishi Electric SD-N50-DC24V is a contactor with a DC 24 V coil, designed for switching loads in industrial control panels where a DC control voltage is the standard — common in PLC-driven cabinets and battery-backed systems. The DC coil draws a continuous holding current once picked, unlike an AC coil that relies on a shading ring. This matters for power supply sizing: the inrush is lower than an equivalent AC coil, but the steady-state draw must be budgeted in the 24 VDC supply's capacity.
