M8, M12, & 7/8'' Circular Connectors

HARTING M8, M12, and 7/8'' Circular Connectors feature straight and angled variants with IDC or crimp connectors for field assembly or a range of pre-assembled overmolded connectors. The M8 and M12 circular connectors are mainly used for the cabling of sensors and actuators. The 7/8'' circular connectors are primarily used for DeviceNet applications and power supplies. The range of these HARTING M8, M12, and 7/8'' connectors are further enhanced with a wide selection of solutions for the device side, such as panel feed-through, PCB adapters, and gender changers.
