In fact, the male and female connectors according to DIN are a bit outdated. But I needed two for a transformer. The quality is not very high. Since DIN connector just comply with the standard HiFi, the expectation of the quality should also not be overestimated. Cable to 4.0 mm² can be screwed firmly. Must mm² at 4.0 but already well bundled, best tip to be easily soldered, otherwise it does not fit and you have to cut some wires. The covers, here green, not particularly hold and fall off easily.
