G-WIR	G-WIR, knitted wire meshes can be delivered in various materials and a huge bandwidth of diameters. Through the type of knitting the G-WIR material is elastic. It is an ideal contact material to accomplish electric conductivity between housing and cover. The knitted wire establishes a continuous and complete shielding. This type of gasket is not a weather gasket. The G-WIR material is especially adapted for rarely released connections. Otherwise the resilience of the material would be suffered from being compressed frequently. For contact connectivity, which are frequently opened and closed, we recommend knitted wires with internal elastomer core G-WIR-E.
G-WIR-E	G-WIR-E shielding wires join the excellent compression ability of solid, foamed or tubular elastomer wires with the conductivity of knitted mesh. The outcome of this is a very high connectivity. The material is available in a huge range of diameters as well as metal and elastomer combination for different requirements. The elastomer core is surrounded by two layers of mesh normally. Up to seven layers can be delivered to raise the attenuation, but the compression rate of the wire falls related to the amount of layers. Normally two layers achieve enough attenuation in practice. More than four layers should not be chosen. Else the compression rate will be much limited. G-WIR-E with up to four layers metal mesh directly returns to its origin after compression. Therefore it is an excellent EMC seal for doors or housings, which are frequently opened and closed. This type of EMC gasket is not a weather gasket. Gaskets join the brilliant compression abilities of elastomer with the conductivity of knitted mesh. Out of this results a really good connectivity for several application.
G-COMB	Knitted metal mesh and elastomer core with knitted mesh are effective and cost-efficient EMC seal solutions, but nonetheless they have essential disadvantages in a few situations: 1) They are no seal against environmental influences. 2) They can not be mounted easily on flat surfaces. These problems are solved with G-COMB. G-COMB is a combination of an elastomer foamed rubber and elastic knitted metal wire sideways. The elastomer strip can be delivered self adhesive to add it to metal surfaces easily to avoid using special, additional adhesives. Usually the elastomer is mounted to the outside to get an air- and environmental finish.
G-TEX $G-TEX$	G-TEX conductive textile gasket with different profiles, self adhesive or as clip on. Inside core is out of polyurethane foam (bromine free too) UL 94 HB/V-O listed, coated with laminated textile material out of Ni/Cu, Ag/C or monel, 3D-conductive foam, I/O panel- and D-Sub gasket as well as conductive adhesive.
G-WEB	G-WEB is a combination out of a knitted aluminium mesh cloth and an elastomer. The filling produces an environmental seal. G-WEB is a cost-effective possibility to seal small parts of surfaces with less than 0,05 mm unevenness. It is used to seal multi pin connectors (D-SUB, HDMI etc.) for example. G-WEB elastomer filled aluminium wire mesh can also be delivered in stripes up to 300 mm width as well as customer specific die cut gasket.
G-SPAN	G-SPAN is a material combination out of die cut monel or aluminium for EMC shielding. Additionally G-SPAN can be filled with fluor or solid silicone to obtain an environmental seal. The material is made for applications with an evenness less than 0,1 mm. G-SPAN is a cost-effective possibility for sealing foundings or milled surfaces. G-SPAN can be delivered in stripes up to 300 mm as well as die cut. For most application a filling with solid silicone is recommended. In exceedingly aggressive surrounding, for example if the material is getting contact with oiling, hydraulic fluids, petroleum or aeroplane fuel, it is recommended to choose fluorine silicone as filling material. If there is no need of an ecological seal, G-SPAN can be delivered without silicone filling.
G-PIK	G-PIK is a material combination for EMC sealing composed of small monel or aluminium wires vertically vulcanized into solid silicone - a brilliant weather gasket. The embedded wires are lightly crimped and obtain a maximum of elasticity due to this. The wire material density is 140 or 185 wires per square centimetre. In exceedingly aggressive surrounding, for example if the material is getting contact with oiling, hydraulic fluids, petroleum or aeroplane fuel, it is recommended to choose fluorine silicone as filling material. Besides the good HF shielding, G-PIK is a weather-proof sealing. The evenness of the surface should be less than 0,5 mm. G-PIK is available in stripes up to 114 mm width and 900 mm long. On special requests lengths up to 20 m can be produced. For this purpose the available thickness starts at 0,5 mm and up to 12,7 mm. Naturally die cut gasket are possible as well.
G-PIK-S	G-PIK-S accords to G-PIK with the difference, that the silicon is foamed.
G-SIL	G-SIL is a shielding and sealing material out of silicone elastomer. It is evenly spread with silver- or nickel-plated particles to obtain an electric conductivity. For assembly a conductive adhesive is recommended. With it G-SIL can be connected with each other as well as with metal surfaces. Non conductive adhesive has to be used with care. Additionally it has to be taken care of the continuous conductivity between housing or cover and sealing. Epoxy resin, conductive or not, are generally not qualified for the adherence of silicone elastomer. By request adherence on customer parts can be conducted.
G-FRAM	G-FRAM consists out of an aluminium profile border with an edgewise added shielding string as mechanically self carrying and electric and high frequency well shielding sealing for larger opening like doors of shielded rooms. The metal border is used to fasten the part as well as mechanical pressure limitation to avoid compression out of range for the shielding string. G-FRAM is solid, dimensionally stable and eases the mounting where is can be difficult to exactly fix a normal flexible shielding material on a long distance. An additional advantage of G-FRAM is the fact, that it can be easily removed to prevent damage, when rooms or doors have to be demounted. G-FRAM is made out of an aluminium flat profile with an edgewise added knitted full metal mesh with or without elastomer core. A further alternative for this is the differential equipment of the flat profile, where for example one side can be equipped with an electric and the other side with a weather sealing. For this case the gasket can be made out of neoprene or silicone, which will be added on the small side of the profile frame with a suitable adhesive.
G-PULS	An electromagnetic pulse includes bundled energy for a really short period. The energy level is very high and a big part of this energy is in the lower frequency spectrum. Specification were drafted to protect against this energy, especially with a high attenuation against magnetic fields. Values from 60 dB at a frequency from F = 10 kHz or 80 dB at f = 14 kHz are typical therefore. Housings, cabinets, chambers and honey comb vents out of aluminium offer a high protection against the electric field, this means for energy in the high frequency spectrum. In this range the shielding is achieved by adding a as conductive as possible surface between the protecting area and the striking energy. A big part of the energy will be reflected as well as absorbed. But shielding against a magnetic field requires a material, that has a high magnetic permeability as well as a high electric conductivity. The material mostly uniting these properties is stainless steel. Furthermore stainless steel is a cost-efficient solution. G-PULS EMP air cover made out of evenly spread steel honey combs, bordered by a customer specific frame for mounting with standard dimensions up to 1000 x 500 mm. Larger dimensions have to be discussed with the customer due to cost effectivity. Customer and application related wishes in relation to the size, form of the border and the surface coating are possible.
G-FIL	G-FIL shielded air vents offer a high grade of shielding effectiveness against the penetration or emissions of high frequency interferences of all kinds through air vents of otherwise shielded housings. The air flow resistance is very low. A G-FIL air vent consists out of a aluminium honey comb bordered by a frame. Honey comb and frame are made out of a hard aluminium alloy. The frame of the vent is delivered with fixing holes or tapped through holes to fasten the air vent to the housing. The frame normally has a gasket to seal the space between the frame and the housing. The air vents are usually produced by specifications of the customer. Possible forms are round and rectangular. Frames manufactured out of aluminium are usually used for rectangular profiles. Round vents are hold by two round profiles.
G-DUST	G-DUST, shielded air vents with additional dust filter offer a high grade of shielding against penetration and emission of high frequency interferences of each king at air openings. They protect against dust additionally being sprayed with thixotropic oil. Thereby the whole dust is bonded and anticipated that it deposits inside the housing. Using dry filters results in a minor protection against dust. A G-DUST vent consists out of three layers of wavy wire mesh, which are enclosed into a double grid of expanded metal. All materials consist out of aluminium. The frame border will be provided with fixing holes or thread inserts to fix the air vent. The frame border has generally a EMC gasket for an effective high frequency shielding between the air vent and the housing. The air vent are typically manufactured and delivered in customer supplied specifications. They can be rectangular or round. For rectangular profiles the frame is usually made out of aluminium standard profiles., round profiles will be hold by two round matching profiles.
G-FLEX	G-FLEX is suited for an effective electro static and electro magnetic shielding of cables and cable harnesses. G-FLEX is used like an overlapping bandage around the cable. The shielding tape is knitted as a sock like, round tube of metal mesh and will be compressed afterwards. The result is a double layer band. If the material is overlapping with 50%, the result is a four layer, very effective shielding.
G-VIS	Many electronic devices like for example LCD-fields plasma display or screens with cathodic tubes have indicator display with LEDs or lamps. All those display have to be optically transparent for their purpose. But additionally they are often permeable for high frequency radiation. Even if the complete housing is shielded to be insensitive against interferences and for data integrity, the indicator display interfere. They are a vulnerability in the high frequency shielding. Germania elektronik offers G-VIS, shielded windows for the shielding of display, to correct this vulnerability. Because of the variety of current and future display, as well as the adjustment of windows for the housing design and form, shielded windows will be manufactured and delivered especially according to the application. It is obligatory and the users advantage, that the manufacturer developes the best technical and economical solution for the shielding of display together with the user.
