The M12 connector, which has proven itself in industrial applications, is also a top performer in outdoor applications. The use of specific materials makes this possible.

Industrial environments would be unimaginable without the classic M12 connector. Data, sensor and power applications are all mastered by the M12. The connector’s manufacture relies on well-known materials and production processes: die-casting, injection molding and turning technique all enter the picture.

Increased flexibility and the decentralization of facilities are associated with a growing need to also deploy connectors in harsh environments, as well as outdoors. Today, connectors are expected to feature adequate encapsulation against salt spray and mist, which in turn requires more resistant materials.

For this reason, HARTING Technology Group tested the use of especially durable materials. However, stainless steel in V2A quality is not sufficiently resistant – the suitable higher grade material is referred to as V4A.

Processing V4A, however, is problematic: series production readiness and reliable machining cannot be guaranteed by the use of conventional machines and tools. The elements of material and tool must be coordinated with one another. The material itself must meet the most rigorous standards, which is not the case for some of the materials on offer. While they are easy enough to process, they fail to demonstrate adequate resistance in the field.

On the manufacturing side, HARTING Technology Group has succeeded in tackling V4A grade stainless steel. As a result, this means that M12 crimp connectors in V4A are protected from extreme salt spray and mist. HARTING has proven this in tests that conform to IEC 60068-2-52 severity 4. Consequently, this has demonstrated that the M12 connectors are robust and suitable for scenarios in the harshest of environments.
