Application

This shielding gasket solves problems of microwave shielding that no other gasket can solve and is
particularly used for military and aerospace applications. Its competitive cost also enables it to respond to
commercial applications requiring high protection. 4

MATERIAL
Spiral: Tin-plated beryllium copper (RoHS compliance).
Cord: 80 durometer PVC (hard plastic).
SHIELDING PERFORMANCE
143 dB at 10 GHz
165 dB at 1 GHz
COMPRESSION FORCE
Optimal compression of the gasket is 25% of the diameter of the spiral. The compression forces given are
approximate:
Standard Force: 5.5 kg/cm
Moderate Force: 1.8 kg/cm
Low Force: 0.3 kg/cm

Available options

CUSTOM SIZES
We can manufacture cord gaskets with all sizes of diameters, from 0.86mm up to approximately 38mm.
There is no additional cost for a specialized diameter. However, for large cords, the length of the gasket
available is smaller.

PLATING
Plating options can be specified by adding a prefix before the part number:
EIW: RoHS compliant edge tin plating for high humidity or salt fog
(Example: GTS-EIWMS-318).

RoHs Tin- Specify plating by choosing the
Material Force plated edge desired prefix from the table. Additional plating options are available
Standard EIWSS Example: GTS-EIWLS-475 by special request: Gold (Au)
Beryllium Compliant edge tin plating and Nickel (Ni) Sulfamate.
copper Moderate EIWMS RoHS
Low EIWLS Low hardness

CORD INSERT
Moderate and low force gaskets come standard with PVC cord in the center of the spiral. The cord acts as a
mechanical stop to protect the spiral from over-compression during use and handling. Specify “no cord” in the
moderate and low force gaskets if you want a gasket without cord.
NC: No Cord (Example: GTS-IWMS-318 NC). All Standard Force gaskets come without cord
(no NC required).

SPECIAL CORD
Special cords can be specified as follows (may not be available in all sizes and may include extra charges):
-F: Solid Fluorosilicone Cord (example: GTS-IWMS-318-F)
-O: Aerospace Qualified Silicone (low degassing rate)
-S: Solid Silicone Cord
-T: Thermal Plastic Rubber Cord
