Inter-8® Weave Cable has applications to many interference problems. Current-carrying conductors generating interference fields can be replaced with INTER-8 WEAVE cable to substantially reduce radiation. In low impedance circuits where external interference results in disturbing signals, Inter-8® Weave Cable will reduce the circuit sensitivity to the external fields. Among typical applications are cable connections to strain gages, thermocouples, photoelectric detectors, audio coils and transformers, piezoelectric transducers and preamplifiers.
SPIRA-SHIELD is flexible conduit that provides high permeability magnetic shielding for sensitive cables and conductors. Constructed of .010" thick CO-NETIC AA Alloy, SPIRA-SHIELD provides greater attenuation than braided sleeving and also furnishes physical protection. Among typical applications are ground support and communication equipment, shipboard control systems, audio-level interconnections, sensitive instrumentation and aerospace apparatus.
Co-Netic® Braided Sleeving, constructed of 36 or 34 AWG CO-NETIC AA high permeability wire, provides superior flexibility compared to foil that is spiral or channel wrapped around cable.
CO-NETIC AA wire in .005" diameter is widely used in magnetic shielding braid applied over cables. All gauges have applications where high permeability, low coercive force and ferromagnetic properties are required. CO-NETIC AA wire is corrosion resistant and has an affinity for solder. Meets MIL-N-14411, Composition I.

Connector Gaskets are seamless EMI die cut flange seals in an assortment of materials and thickness. Selection of material is dependent upon shielding and pressure sealing requirements. Standard industry shell sizes with holes or U slots or custom sizing is available. Connector gaskets are used for military or commercial applications.
|
|
Connector gaskets can be die-cut to specification. They increase the electric continuity between connector gaskets and boxes.
The texture, homogeneity and chemical composition of the silicone base is not changed or modified by the presence of metal wires. The tolerance of NEOSIL F to
chemical corrosion and vibration as well as its durability are the same as for pure silicone. The presence of wires running perpendicular to the surfaces, but contained in the mass of the material, does not affect the airtightness or watertightness performance of NEOSIL F. In addition, since Monel wire ensures good compatibility with most metals, even the slightness galvanic corrosion is rarely detected between NEOSIL F gaskets and its support, even in aluminium.

New Progress EMC Series 85 cable gland
Low-impedance termination, variable shield tap through 360º with low transfer impedances
The development of the new cable gland – the Progress EMC Series 85 – had one primary aim: to improve the shield clamping area for each cable gland type significantly to give users more flexibility.
For this purpose a completely new collet chuck was developed. Ingenious segmentation of the collet chuck gives it optimal shield contact. The individual segments slide together when the cable gland is mounted to produce concentric shield termination (see figure). This guarantees vibration-proof implementation that is pull-out resistant.
These new, innovative EMC cable glands (patent pending) make it possible to cover a large shield clamping area with very few types.
Progress EMC Series 85 cable glands are ideal for high leakage currents. For this reason they are particularly well suited for use in power engineering, railway technology, and plant engineering among other areas.
The new type series includes M16 to M63 metrical versions for shield diameters of 3 - 44 mm and Pg 11 to Pg 29 for shield diameters of 6 - 33 mm; these are available from stock.

These EMI Shielding Gaskets are realized covering one soft foam of Polyurethane, Silicone or Neoprene with conductive polyester woven (Nickel or Tin-Copper electroless or galvanic deposit on all single polyamide yearns and then weaved).
This contribute to obtain excellent efficiency shielding and invariability in the time of the conductivity value (until 0.08 Ohm/sq - value max).
The sizes are square, rectangular, circular or "D" but our equipment, however, allow different form sections.
The installation, usually, is realized by a biadhesive tape laid on a side of the gasket (standard).
Considered high abrasion resistance of covering woven of these gaskets, ideal use is on cabinet doors subject to frequent openings, therefore where it is normally desired a puny clothing strength.
