SPIRA MANUFACTURING

Ultra Quick-Shield

Ultra Quick-Shield offers excellent shielding at an affordable price. The spiral is wound out of low cost spring temper stainless steel for excellent spring memory and compression set resistance. The spiral is tin plated for superior conductivity and shielding properties.

The affordable cost and superior shielding of this gasket makes it an excellent choice for high end commercial applications. Combining it with a die-cast or molded “pinch boss” groove gives you the optimal price/performance combination.

MATERIALS

Spiral: Tin/lead plated stainless steel. (See Options for RoHS compliance). Electroplated, 90% tin, 10% lead (edges unplated).Cord: “No cord” is the default to keep costs low. See Options if cord is desired.

SHIELDING QUALITY

These gaskets can offer shielding quality in excess of 150 dB at frequencies between 100 kHz and 1 GHz. The shielding quality may vary depending on the specific application.

COMPRESSION FORCE

Ultra Quick-Shield gaskets come in three different resiliencies (as shown below). Optimal compression of the gasket is 25% of the diameter of the spiral. Since the force to compress the gasket is a function of the cube of the thickness of the stainless steel ribbon, the compression forces shown are approximate.

Standard Force: ~30 pounds per linear inch compression.Moderate Force: ~10 pounds per linear inch compression.Low Force: ~1.5 pounds per linear inch compression.

MOUNTING

This gasket is groove mounted.
