Yaskawa Electric Corporation HI-12E AC Magnetic Contactor

The Yaskawa HI-12E is an AC magnetic contactor rated for up to 18 A, designed to switch motors, transformers, and other electrical loads in CNC control systems and industrial automation, including CNC machines such as Mori Seiki equipment, with a typical 200–240 VAC coil and load rating. It operates by energizing a coil to close or open the normally open main contacts, enabling remote switching and protection within control circuits. Common uses include spindle motors, coolant pumps, auxiliary equipment, and other motor-control tasks in CNC systems and industrial automation, with installation options that include panel mounting, DIN mounting, or screw-mounted configurations depending on the setup. Today the HI-12E is typically found as a surplus or legacy component, with Fuji Electric SC-E02, Mitsubishi S-T12, and Schneider LC1D18 listed as common replacements.
