Application
Due to their outstanding material and
electrical characteristics, beryllium copper
fingers of different shapes and dimensions
are used in the following industries:
Broadcasting, telecommunication, industrial control, measuring and instrumentation, aerospace technology, nuclear physics and data processing. Contact fingers
and rings made of beryllium copper are
used at all radio and microwave frequencies, for instance as contacts to valves
and tuning components as well as for
shielding.

Material Properties
Material Options
The beryllium copper (CuBe2) used for
our products is a quality tested quench
hardening spring material. It is noteworthy
for its yield point, tensile strength and
elasticity, good electrical conductivity,
high fatigue strength as well as its resistance to abrasion and corrosion. The
good thermal conductivity coupled with
hardness eliminates sparking. The raw
material is non-magnetic and has an
excellent temperature performance.
• Material: hardened or unhardened
• Finish:

Specialist for Contact Springs
Contact strips made of stainless steel
The company Feuerherdt GmbH now offers, as first supplier, a regularly stocked assortment of contact strips made of stainless steel (German material no. 1.4310). The material
used is stainless strip steel for springs: a material with extraordinary toughness, good
spring characteristics, and long service life. The anti-corrosion properties are excellent,
with the result that the contact surfaces are always smooth and shiny. The shielding
properties are good, but the damping values that can be achieved are less than with BeCu.
Material number: 1.4310
Characteristics: stainless steel,
spring band steel, cold-rolled
DIN 17224, EN 10258

Contact strips made of stainless steel
Curved and slippy fingers can be used to shield housings, enclosures and panels very effectively against interference.
They are optimal to use when space is short. Assembly is extremely simple as the rear side of the strip is provided
with two-sided adhesive strip.
Extensive soldering, riveting or bolting is therefore not necessary. The measured attenuation values are excellent.
Magnetic field: at 14 KHz more than 46 dB. Plane waves: at 10 GHz approx. 108 dB.
Slippy fingers are a further development of the curved fingers, whereby the free part of the finger is retained within
a channel and is therefore protected against damage. As compression increases, the fingers will slide further into
the channel.

Spiral Shield Gaskets
Spiral shields are made from bands of tin-plated beryllium copper or stainless steel.
The spirals are laid into a groove so that they are well protected against destruction. The groove can be milled in
the metal or introduced during the pressing process. If neither option is feasible, the spiral can be supplied with a
silicone strip which keeps it in the proper position and at the same time acts as a stop to keep the material from
being deformed too much.
The spiral shields can also be supplied with a silicone foam which provides protection against dust and humidity.
Tin-plated beryllium copper offers the best shielding and is one of the few materials with corrosion compatibility
with aluminium if humidity or salt water spray is a problem.
Stainless steel shields are used if the corrosion-resistance of stainless steel is important or if the requirements for
elasticity and shielding properties are lower and a more economical option is preferred.
Gaskets can be supplied with three levels of resilience: Standard Force. Moderate Force and Low Force. The Moderate and Low Force gaskets have an inner core of solid silicone with a diameter some 75% of that of the spiral and
stops it being deformed past its elastic limits.
Both types can also be ordered without the core by adding NC behind the order number (e. g. MS-08 NC). The
stainless steel spirals are supplied as standard without the silicon core. They can be ordered with core by leaving
the NC off the order code.

Spiral Shield Gaskets
In order to compress the „Spira Shield“ gaskets by 25% of their diameter the following forces are required:
Standard Force:
Moderate Force:
Low Force:
30pounds per linear inch of the gasket
10pounds per linear inch of the gasket
2pounds per linear inch of the gasket.
Spira Strip (Military Grade)
Spiral gasket with tin-plated beryllium copper and elastomer seal
Spira Strip is a Spira shield gasket to which a strip of solid or foamed elastomer has been attached. The elastomer is
provided with adhesive tape to keep the spiral in the required position. Solid elastomers also serve as a mechanical
stop to protect the spiral gasket from excessive compression as well as acting as a seal.
Foamed elastomers are preferred as environmental seals against rain, wind and dust.
Solid silicones have a Shore hardness of approx. 40°. They can be supplied as fluorosilicone if the „S“ from the order
number is replaced by an „F“ (e. g. SS-0622/F).
Moderate Force und Low Force spirals have a solid elastomer core of approx. 80 Shore and a diameter some 75%
of that of the spiral.
The Moderate Force spiral can also be ordered without the elastomer core by adding „NC“ to the order number (e.g.
MS-0834 NC/S).
Foamed silicones are supplied with Shore hardness of 15°-25°. They can also be replaced by a neoprene foam if the
„C“ is replaced by „A/P“ (e.g. MS-0623-A/P).

These spiral seals have a specially formed elastomer seal
for use with very uneven sealing surfaces. Their design
allows the elastomer seal to act both as pressure stop to
protect the spiral shield gasket and also as a seal against
dust and moisture.

Shielded Windows
Shielded windows are fully transparent but provide effective electromagnetic screening.
They consist of two layers of glass, polycarbonate or acrylics sandwiching a fine metallic gauze which extends beyond the edges of the
pane allowing good contact.
Windows of glass or polycarbonate can be made of two sheets of identical
dimensions or with a step-construction.
.
Gauze
Sheets of same dimensions
.
Step construction
Acrylic sheets are glued over the whole area. The windows can be
produced by cutting to size, either with straight or stepped edges. Silvercoating is used to provide electrical contact.

Electrically Conductive Elastomers
In addition to contact finger strips and woven gaskets
the electrically conducting elastomer seals form the third
major group of shielding products.
Electrically conductive elastomers are produced in
sheets, as moulded or extruded sections and can also
be printed onto surfaces.
They consist of an elastomer binder (silicone or fluorosilicone) and a silver filler. Depending on the technical
requirements this may be silver-coated copper or aluminium particles, silver-coated glass balls or particles of
pure silver. In addition nickel, nickel/graphite and carbon
are also used as filier.
Depending on the numbers required rings will be either
moulded or supplied as vulcanised round cord.
Extruded circular profiles can be produced with very
small diameters and are therefore ideally suited for
enclosures with thin walls. This option is particularly
cost-effective.
Elastomer seals have very good attenuation properties.
lying between 50 and 120 dB depending on the product
and wavelenght. They also act as seals against dust
and water.

Galvanic corrosion
This type of corrosion occurs if two materials with different electrochemical properties come into contact in the
presence of an electrolyte such as salt water. The type of gasket used must also be considered carefully because of
the metal fillers involved. Galvanic corrosion is a problem outdoors particularly in marine environments.

Mesh gaskets are deformable EMI shields made from
knitted wire. They can be supplied with rectangular or
circular cross-section. The fine-meshed knitted material
has excellent elasticity and is very adaptable ensuring
good contact and shielding.
Materials
All Mesh Gaskets from stock are made either with Monel
(a copper-nickel alloy) or in a simpler version with tinplated copper clad steel wire. Of course other materials
such as stainless steel, aluminium or beryllium copper
can also be used if so required.
Available forms
Knitted wire shielding can either be supplied on spools
or as ready-to-use closed ring gaskets to customer
specifications.
Finished gaskets are provided from 75 mm diameter
or 50 x 50 mm.
Customers should note the following tolerances when
ordering:
up to175 mm: ± 0.76 mm
176 - 254 mm: ± 1.52 mm
above 254 mm: ± 1.52 mm for every 254 mm.
Round and double round knitted shields can be supplied
with a knitted fin or connection by means of which they
can be fixed in place.

Mesh-Elasto (Elastomer Core and Knitted Wire Cover)
Mesh-Elasto is a deformable EMI gasket consisting of a
circular or rectangular core of neoprene or silicone foam
(or a silicone tube) around which there is a single- or
double-layer knitted wire cover.
As with normal mesh products the knitted wire ensures
electrical conductivity while the highly deformable
elastomer core improves elasticity and contact.
In addition to HF shielding gaskets can also act as seals
against dust and water.
Materials
All gaskets from stock are made either with Monel (a
copper-nickel alloy) or in a simpler version with tinplated copper clad steel wire. Of course, other materials
such as stainless steel or aluminium can also be used
if so required.
Available forms
Mesh-Elasto can either be supplied on spools or as
ready-to-use closed ring gaskets to customer specifications.
For made-to-order rings you should state both the
diameter and the straight length.
Please note the following tolerances when ordering
up to 175 mm: ± 0.76 mm
176 - 254 mm: ± 1.52 mm
above 254 mm: ± 1.52 mm for every 254 mm
Round and double round knitted shields can be supplied
with a knitted fin or connection by means of which they
can be fixed in place.

Kombi-Shield:
Mesh+Elastomer Enviro-Seal
Mesh-Elasto+Elastomer Enviro-Seal
Kombi-Shield consists of a Mesh or Mesh-Elasto gasket
which is connected on one side to a foamed or solid elastomer
seal. This can be supplied with or without an adhesive tape
for fixing purposes.
Standard is a fully-metal knitted wire gasket with an attached
band of elastomer foam.
Versions with Mesh-Elasto can be supplied to customer
specifications. In this case the knitted-wire gasket has an
elastomer core of neoprene, silicone or silicone foam. The
knitted-wire is usually V2A or Monel. The soft core means
that the Mesh-Elasto achieves a closer fit. By combining the
Mesh or Mesh-Elasto gasket with an outer strip of elastomer
it is possible to achieve both good EMI shielding and environmental sealing against dust and water.
Available forms
Kombi-Shield can be ordered by the metre in various dimensions or to customer specifications.
Materials
Monel wire and tin-plated copper clad steel wire are used for standard products. Specially ordered Mesh-Elasto
products are covered with Monel or V2A.
The elastomer seals are neoprene or silicone (either foamed or solid).

forces.
These inexpensive EMI-shields are easy to install and
have been developed specially for commercial applications.
They can be installed in a groove or simply stuck onto the
surface in question using a double-sided adhesive tape.
In addition to attenuation of approx. 60 dB from 30
MHz to 1 GHz. the gaskets also act as seals against
dust and water.
Materials
A core of polyurethane foam is covered by a jacket of
silver-coated nylon.
The gaskets offer very good restoration forces alter
deformation.

Conductive Foils
Conductive foils are suitable for a wide range of applications in shielding technology. They are inexpensive
and easy to use. They are usually supplied with a conductive adhesive tape.
Typical applications include the lining of small enclosures, sealing of housing joints and welds, establishing
electrical contact on surfaces which cannot be welded,
shielding cables as well as the short-term use during
EMC measurements in order to locate leaks for covering
points which come into question.
