The HARTING 21033812404 is an A-coded M12 PCB adapter designed for surface mount technology (SMT) applications. It provides a secure and reliable connection in industrial automation, power transmission, and data communication systems. The adapter's robust construction and A-coding ensure compatibility with standard M12 connectors, while its varying pole configurations (4, 5, or 8) allow for flexibility in circuit design. It is RoHS compliant and operates within a temperature range of -40°C to +85°C, making it suitable for harsh environments. Contact material is copper alloy with Au over Ni plating for the mating side, and the insulator is made of LCP.
