HARTING’s Stainless Steel M12 INOX Connector Resists Harshest Conditions

HARTING’s new M12 INOX connectors are made of high grade stainless steel to provide superior corrosion resistance in harsh environments, indoor or outdoor. M12 connectivity is standardized and reliable, widely used in industries like transportation, factory automation and robotics. M12 connectors stand up well in most applications, even outdoors, but when the operating environment is especially harsh – for example, extreme salt spray or mist – a stainless steel connector like the IP 65/67-rated M12 INOX is required.

Today’s connectors for such environments are expected to feature adequate encapsulation against salt spray and mist, which in turn requires more resistant materials. HARTING tested especially durable materials in developing the M12 INOX. It settled on superior V4A grade stainless steel rather the widely used V2A grade, and adapted its manufacturing processes to suit the raw material. The connectors are made with V4A that’s free of flaws to ensure that the connectors meet the IEC 60068-2-52 severity 4 standard.

The M12 INOX is designed for an ambient temperature range of -40oC to +85oC, and up to 500 mating cycles, rated for up to 4A and 250V with crimp termination. HARAX termination (IDC technology) also is supported. The M12 INOX is available in A (5 pole male), B (5 pole male and female) and D codes.


The HARTING Technology Group, family owned and based in Germany, employs more than 4,300 people globally with subsidiaries and branch offices in 40 countries. With production facilities in Europe, Asia, and the Americas, the HARTING portfolio of connectivity solutions focuses on multiple levels, from the machine to the device and into the communication infrastructure. The U.S. facility in Elgin, Illinois is one of three HARTING locations that manufactures the HIS product line (HARTING Integrated Solutions - backplanes) and custom cable assemblies. HARTING also has custom cable assembly capabilities in Mexico and Brazil. The company’s core business is intelligent and high-performance connection technology. HARTING works in almost all industrial markets with a focus on requirements for robust, reliable connectivity solutions.
