High shielding performance from
conductive O-rings
Holland Shielding Systems has developed a new series of O-rings for EMI shielding with a very high electrical conductivity, and hence shielding performance.

EMC gaskets for high-performance shielding
Holland Shielding Systems has a range of EMC gaskets that combine high-performance shielding with low closing force, very high compression (80%) and a negligible compression set.
The construction of the O-rings features an electrically conductive layer with very low resistance on a nonconductive rubber core.
As a result, their mechanical properties are comparable with normal O-rings.
Also costs are considerably lower than devices based on electrically conductive rubbers.
A low closure force version is also available, based on a hollow extrusion, and allowing a less rigid construction to be used.
This can also result in a cost reduction.
All profiles are manufactured to the highest precision.
For example, the smallest diameter of 0.8mm can have a hole of just 0.4 mm.
The largest diameter is 18mm.
Devices are also available as flat, rectangular and die-cut versions.
