DIN EN 60352-2 is the German national adoption of the European standard EN 60352-2, which is identical to the international standard IEC 60352-2.
The standard covers crimped connections used in electrical and electronic equipment, specifically: Wire Types : Stranded wires with a cross-section of 0.05 mm² to 10 mm² or solid wires with a diameter of 0.25 mm to 3.6 mm Excluded Items apply to the crimping of coaxial cables
cross-section) and solid wires (0.25 mm to 3.6 mm diameter). Key Requirements: din en 60352-2 pdf
Perhaps the most important metric. The standard defines that for a given wire size and terminal type, the crimp height must fall within a narrow tolerance window (e.g., 1.2mm ± 0.05mm). Too high = loose connection. Too low = severed wires.
Lena walked to the workshop. In the locked tool cabinet, she found the approved crimp tool: a pneumatic press with interchangeable die sets, last calibrated three months ago. Beside it, a crimp height comparator—a precision micrometer block with a slot. For a 0.5 mm² wire, the target crimp height after crimping (the barrel’s compressed outer dimension) was specified in a table in the PDF: typically 1.05 mm ±0.05 mm. Key Requirements : 4
Microsection Analysis: A destructive test where the crimp is cut cross-sectionally and polished. Engineers look for "voidless" compression, where no air gaps remain between the wire strands. 4. Why Compliance Matters Using DIN EN 60352-2 compliant connections ensures:
Workmanship: Requirements for the crimp height, width, and visual characteristics (e.g., no cracked insulation, all wire strands captured). Too high = loose connection
Clause 6 of the standard specifies the minimum pull-out force for a given conductor cross-section (e.g., 0.20 mm², 0.50 mm², 1.50 mm²). A tensile test machine must pull the wire axially from the terminal until failure.
