The ferrule sleeve must be completely filled by the conductor. This should be achieved exclusively by the use of a high-quality Depending on the cross-section, the conductor should protrude precision tool. The result is a safe, reliable connection in both approx. 0 0.5 mm from the ferrule sleeve. D electrical and mechanical terms. 0 0.5 Cut-away view: Weidmller offers a wide product range of mechanical crimping tools. An integral ratchet mechanism with disengaging option guarantees optimum processing quality. Crimp connections Front view: produced with Weidmller tools comply with international standards and specifications. 2 2 2 2 0.5 mm 0.75 mm 1.0 mm 1.5 mm The DIN EN 60352-2 standard recommends that tools and contacts should come from the same manufacturer, since this is the only way to ensure consistently high quality. Otherwise, it is the user who is responsible for the quality. Weidmller tools are designed to fit with Weidmller contacts and thus are in full compliance with the DIN EN standard. 2 2 2.5 mm 4.0 mm For cross-sections 2 650 mm , the crimping shape is approximately the same.
