J7KC / J7KCA Industrial Relays

Omron Industrial Automation J7KC / J7KCA Industrial Relays use bifurcated contacts to offer high contact reliability (5V_DC, 3mA minimum) and high endurance. A coil surge absorber unit is installed as standard. These relays are designed with Push-In Plus wiring technology to save wiring and maintenance time. The space-saving modules also feature a unified 45mm width to help downsize control panels. J7KC Magnetic Contactors are ideal for motor and primary side switches and motor control and safety applications. Omron Industrial Automation J7KCA Auxiliary Relays (Contactor Relays) are the same shape as J7KC Magnetic Contactors, making them suitable for standardizing panel designs.
