19"/10" rack mount unit 1 HU with 12, 16, or 24 RJ45 jacks assembled on one common PCB. No special tooling is required for mounting of the cover (shielded type). The printed circuit board is mounted horizontally. Grounding is done using the enclosed earth connection cable (shielded types). Cables are terminated via IDC (LSA Plus) terminals with color coding according to EIA/TIA 568 A and B. 360-degree shielding can be connected directly on the PCB on a large contact spot using screw clamps, without the need to twist the shielding braid (shielded type). The risk of short-circuit between the screening braid and data leads is minimized due to sufficient space between data terminals and screening contact. A limit of 13 mm maximum of untwisted length of data leads can be easily achieved without restricting easy installation. Enclosed cable ties are provided for strain relief of the cables without the need for screws and special tools. Modular jacks are numbered on the front panel. The housing is made of steel and powder-laminated in light grey (RAL 7035); the cover is made of stainless steel.
