The 05.502.2100.0 is a crimp die "B" component designed for use with Wieland Electric's modular crimping tool system (base tool 95.101.0800.0). This die is specifically engineered for crimping turned contacts with a diameter of 2.5 mm, accommodating conductor cross sections from 0.5 to 4 mm² (20 to 12 AWG). The crimp die "B" is compatible with contact positioner "1" or "3" depending on the application, enabling efficient and reliable contact crimping for industrial multipole connectors in the revoS series and 400V–690V connector lines. This modular approach allows users to employ a single crimping tool with interchangeable dies and positioners for multiple contact types, reducing tooling costs and improving workflow efficiency in electrical assembly operations.
