半田クイックシールド
半田クイックシールド design is the leading low-cost EMI gasket solution, providing excellent value for money without sacrificing performance. The spiral is precisely wound from high-quality spring temper stainless steel, known for its outstanding spring memory and compression set resistance. This guarantees that the gasket keeps a tight and reliable seal over time, even in environments exposed to vibrations or frequent compression cycles. Thus, it is an ideal choice for a wide range of applications where reliable EMI shielding is essential.

Available options
Custom Sizes
We can manufacture cord gaskets with all sizes of diameters, from 0.86mm up to approximately 50mm.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:
SBN: RoHS compliant edge tin plating for high humidity or salt fog
(Example: HDS-SBN-086W)
Additional plating options are available by special request: Gold (Au) and Nickel (Ni) Sulfamate
Cord Insert
These spiral gaskets are offered without cord to have an excellent quality / price ratio. However,if you think that the compression of the gasket may be a problem, for example, when handling,you can order them with cord by not writing the “W” reference (for low and moderate force gaskets).
W: Cordless,
A: Silicone rubber solid,
T: Silicone rubber tube,
F: Silicone foam
Application
This product is perfect for civilian applications, and allows compliance with the EUROPEAN directive 83528.
Material
Spiral: Stainless steel.
Cord: No cord by default.
Shielding Performance
These gaskets can offer shielding quality beyond 95 dB at 1 GHz.
The shielding quality may vary depending on the specific application.
Compression Force
Handa Quick-Shield gaskets come in three different resiliencie (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: 5.5 kg/cm
Moderate Force: 1.8 kg/cm
Low Force: 0.3 kg/cm
