The 1200 series EMC gaskets consist of a core covered with knitted mesh. In most cases the gaskets are made of sponge or hollow extruded elastomer. For applications like EMP or high temperatures a full metal version is available.
The temperature resistance depends on the core material, but ranges from -60°C to 220°C are possible. These gaskets are insensitive to external influences and can withstand harsh conditions very well. Also available with water seal.
The maximum deflection with a sponge elastomer core is approximately 30%, with hollow extrusion 50%. This is why the hollow type is used more often.
For high frequency shielding, foil-based gaskets like Amucor Shield 6800 will perform better, because of their much larger contact surface.
Advantages:
- High attenuation level for lower frequencies
- suitable for use under extreme conditions (military applications)
- wear resistant
- insensitive for corrosion
