These are characterized by space-saving, easy-to-install designs in telecommunications splices, whether in shrink or mechanical versions, as well as in modern building system technology (speech, telephone, and monitoring systems). Stripping, connecting, and insulating are done in one operation. The connectors meet the requirements of DIN 47 627. Solder-free wire connections in splices for telecommunications cables. A suitable parallel crimping tool or equivalent tool must be used for form-fitting crimping of the wire connectors.
