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 make 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.

PLATING To specify tin plating for RoHS compliance, replace the "T" with "IW" at the beginning of the part number. Additional plating charges may apply.

  • IW: RoHS compliant tin plating (Example: IWNL-06 NC)

This gasket is not recommended for high humidity or salt-fog applications because the edges of the gasket are not plated. If high humidity or salt-fog environments are to be encountered, the edge plated version of our Spira-Shield gasket is recommended.

CORD INSERT To keep costs low, we recommend you omit the cord usually used in the spiral. However, if over-compression of the gasket is a concern or problem, remove the "NC" from the part number on the moderate and low force series gaskets.

Example: TNL-06 NC will come without a cord. TNL-06 will include cord. All Standard Force gaskets come without cord (no NC required).

CUSTOM SIZES We can manufacture Ultra Quick-Shield gaskets in any size diameter, from .034" up to approximately 1.5". The functional length of the part may be short at very large diameters. Please contact us with your requirements.

SPLICING OPTIONS Spira has created three standard options to treat the splicing of material in our spool selection.
