2 Electronic Enclosures Technical Information 445/44 Panel Instrument Cases Acc. to DIN 43700/IEC The largest range of housings in "One Piece" moulded plastic The design allows for universal use; the inside of the case is lined with guiding grooves to take cards. On both the front and back are threaded inserts (M2), and on the side are fittings to take fixing clamps. The front frame which is easy to fit securely is normally included in the delivery. The rear wall is also constructed from "Noryl" and fits exactly into the case. Further interesting points: ) For the initial one-off cost of the necessary tools, all the cases of type 445 can be modified to your individual requirement as follows: a) the exact depth of the case b) the position and arrangement of the circuit board guides c) the depth of the indentation to take either the front plate or sheet 2) The Noryl rear wall can also be modified to your own specification for minimal tool cost as follows: a) apertures (e.g. ventilation slots) b) firm's trade name and address in raised lettering Only your cases are produced using these tool kits, so that you can really call your cases your own! For a small quantity, we can machine the cases and rear walls with our modern CNC-machining centre. Excellent properties of the material: The DIN-cases and rear-wall are constructed from glassfibre reinforced Noryl SE GFN2 which has excellent mechanical and electrical properties.

Thermal properties: Shape stability acc. to Vicat ()...50 Fire safety properties: It is self-extinguishing and non-dripping! Flameproof UL 94V On the the EMI recommendation 89/33/EWG become effective. This recommendation is valid within the EC (European Community) and covers all electric and electronic devices which can cause electromagnetic interference or which can be disturbed by such interference. In order to achieve EMI resistance or to avoid transmission of interference it is necessary to cover these devices with a conductive coating. This can be obtained by the use of metallic cases or cases made of plastic, which is usually dielectric, by the use of conducting metallic coating - a saving of costs and weight. Conductive surfaces can be obtained by lining the interior with metal foil, by galvanising, by vacuum evaporation, by metal plasma spraying or by using apranorm coatings. The apra-norm coating is a high quality conductive coating with excellent conduction, excellent Attenuation (d) Silver coating 2. Aluminium 2,5 mm 3. Copper coating 4. Immension plating Frequency corrosion resistance and a convincing costperformance ratio. Technical Information The apra-norm coatings were developed to produce effective screening against EMI and to give protection against electrostatic discharge (or loading) and to earth sensitive electronic equipment. We offer copper coating as standard delivery, as it has high screening properties, is a good conductor and is economical. Physical properties: Surface resistance: < 0,25 Ω/square at 50 µm thickness Attenuation: > 0 d at 50 µm acc. to ASTM ES-7-83 Adhesion: 5 (excellent) acc. to ASTM 3359 Pencil hardness: > 9 Max. application temperature: 95 C 09
