Krone LSA-PLUS
Krone LSA-PLUS (or simply krone) is an insulation-displacement connector for telecommunications. It is a proprietary European alternative to 110 block. The Krone LSA-PLUS system is not limited to telecommunications, as it is also popular in broadcast systems, where audio interconnections and their associated control systems often use krone wiring. Multipair audio cables have been specifically designed for the system by organisations such as the BBC.
History
Krone was developed in Berlin in the 1970s by The Krone Group, a German telecommunications company. In 2004, Krone was acquired by ADC Telecommunications, an American corporation. ADC was later acquired by Tyco Electronics in 2010.
Characteristics
LSA-PLUS is a German abbreviation:
Lötfrei Solderless Schraubfrei Screwless Abisolierfrei No insulation removal Preiswert Cost-effective Leicht zu handhaben Easy to use Universell anwendbar Universal application Sicher und schnell Secure and fast
Compared to 110, Krone can be easily identified by its contact slots arranged at a 45 degree angle to the wire. Unlike 66- and 110-style IDC punch blocks, Krone contacts can be used with stranded conductors. The contacts use silver to inhibit corrosion and require a punch down tool for wire insertion. Krone blocks are also available in versions which can handle frequencies much higher than conventional blocks.
