Versatile EMC and standard 19” rack cases

24-08-2020 | Verotec | Subs & Systems

Rack cases are a fundamental building block of rack mounting systems, enabling electronic, electric and electro-mechanical sub-systems and assemblies to be installed easily in any standard 19” enclosure. For non-adjustable needs, they will be fastened directly to the 19” front and rear panel mountings, or if repeated access is needed, they can be mounted on telescopic slides to allow them to be removed from the front of the cabinet. Verotec manufactures three different designs, available in several different sizes and with several options.

The heavy-duty RackCase PRO is EMC screened as standard, making it especially ideal for housing heavy equipment in electrically noisy environments. It is a 3U high unit, offered in standard depths of 240mm, 350mm and 460mm, with custom depths offered to special order. The side extrusions feature full-length slots on the external face for mounting telescopic slides, inside they have 12 separate channels into which tapped strips or individual M4 captive nuts can be positioned to give secure mounting points for the housed components. It provides users with good all-round access and simple assembly. The conductive finish vented or plain top and base covers slide into dedicated slots; conductive gaskets in these slots stop movement, ensuring conductivity between all components of the assembly. Front and rear aluminium panels also provide a conductive finish.

The Veroshield EMC rack case is especially useful in decreasing cost in larger 19” rack-mounted systems where just some elements of the overall equipment need elevated levels of EMC capability. They are available as standard in three sizes: 1U high and 265mm deep, 2U and 3U high and 365mm deep Typical attenuation figures are more than 110dB up to 10MHz, falling linearly to 40dB at 1GHz.

The standard general-purpose rack cases are available in heights of 1 U to 6U and depths of 250mm, 350mm and 450mm. User can specify either vented or unvented top and base covers, a 3mm clear anodised or 2mm black painted steel front panel and optional grey or black front handles. They can be provided with or without a rear panel, and all sizes are fitted with mounting locations for optional slimline telescopic slides. To ensure that heavily loaded units are properly supported, chassis runners rated at 50kg are available as optional extras.
