Available options
Spiral mterial
“D” Multi-Seal comes standard with a tin plated Spira-Shield gasket. Other spiral materials or plating may be
specified by choosing a different prefix from the dimension table.
1. Choose the desired gasket from the table based on size and force.
Example: HDS-MBS-358E, moderate force, E=3.58 mm, D=1.6 mm
2. Substitute the prefix from the table below based on spiral material and plating.
Example: HDS-MBS-358E, moderate force , tin(Sn) plated BeCu.
Cord insert
Standard force gaskets come without a cord. We also recommend you omit the cord in moderate force gaskets specifed by “NC” (no cord) in the part number. If over-compression of the gasket is a concern or problem, remove the “NC” from the part number on moderate force gaskets and PVC cord will be included.
Special cord
Special cords including solid fuorosilicone, solid silicone and thermal plastic rubber are available in some sizes.
Application
Handa “D” Multi-Seal Gasket is a kind of EMI and environmental gasket.It is highly suitable for applications that require outstanding sealing, have relatively limited space or aim to employ a groove-mount solution.
Material
Spiral: Spira-Shield, Tin (RoHS compliance) plated beryllium copper.
Elastomer option: Solid silicone rubber, 40 durometer on 3.58mm and 4.75mm; 60 durometer all other sizes. (See
Options for RoHS compliance or other material choices).
Shielding performance
86 dB to 165 dB
Compression force
“D” Multi-Seal gaskets come in two different resilience (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 beryllium copper ribbon, the compression forces shown are approximate.
Standard Force: 5.9 kg/cm
Moderate Force: 2.3 kg/cm
