The ECP 400 series of soft EMI shielding gaskets can now be supplied cropped to any length up to 2m and in customised format.

The ECP 400 series of soft EMI shielding gaskets can now be supplied cropped to any length up to 2m and in customised format.

Short cut lengths can be supplied die-cut on backing sheets for ease of handling at the production assembly stage.

The ECP 400 series soft EMI shielding gaskets comprise a conductive fabric bonded over a soft nonwicking thermoplastic polyurethane (TPU) closed-cell foam.

The gaskets are ideal for shielding applications where high performance levels over a wide frequency range are required and particularly where low closure forces combine with a requirement for good environmental sealing.

All gaskets feature a self-adhesive strip to aid location and mounting.

A wide range of standard profiles is available cropped to any length up to 2m encompassing rectangular, flat, square, D-shaped, V-section, clip-on D-shaped, knife-edge, P-shaped, U-shaped, L- or J-shaped, keyhole and circular.

In addition to standard shapes, TBA ECP can provide custom designs with virtually no limitation to the design of the gasket profile.

Tailor made die-cut shapes can be produced.

Various finishes are available including nickel/copper (Ni/Cu) plated as standard and gold plated for higher attenuation.

Typical specifications for polyurethane foam include UL94V0 flammability rating and 6% maximum compression set.

The conductive fabric is woven polyester (nonwoven option available) and surface resistivity is 0.05ohm/sq.

Offering excellent abrasion resistance, overall shielding effectiveness is 68 to 88dB from 30MHz to 1GHz with a temperature limit of +200C.

TBA's ECP 400 soft gaskets extend the company's comprehensive line of EMI shielding products that also includes knitted wire mesh gaskets, woven wire sheet, metal foil tapes, oriented wire in silicone rubber, moulded and extruded conducting elastomers, printable EMI shielding elastomers, EMI shielding windows, honeycomb vents, shielded fan vents and quiet vents.

The company also offers an extensive line of beryllium copper and stainless steel fingerstock for all EMI shielding applications.
