The OMRON J7KC Series Magnetic Contactor J7KC-12-01 AC100 is an AC-operated electromagnetic contactor measuring just 45mm × 46mm × 67.5mm, making it the world's smallest in its category. Featuring Push-In Plus wiring technology, it significantly reduces wiring and maintenance time. It is ideally suited for controlling AC-3 class motors with power ratings up to 2.2kW (200-240VAC) and 5.5kW (380-440VAC), and can also function as a primary-side switch. The device achieves high contact reliability (minimum 5VDC, 3mA) through split contacts, incorporates a standard coil surge absorber unit, and complies with major safety standard certifications. Furthermore, its mirror contact mechanism with feedback functionality renders it suitable for safety-critical applications, offering broad compatibility with diverse equipment including conveyor motors, compressor motors, pump motors, fan motors, and gantry motors.
