EMI/RFI Performance
Compression Set – Compression set affects shielding per- EMI / RFI Cabinet Systems
formance because gaskets that have taken a “set” do not
properly flex to effectively seal around irregularities on the
sealing surfaces. Equipto Electronics uses finger stock gas-
kets in a “wiping” action that minimizes the effect of com-
pression set. Where foam is used as a base gasket material,
compression is controlled by hardware design that allows
proper contact, but prevents damage from over compression.
Physical Gasket Interface w/enclosure – The gasket / enclo- Available Gasketing
sure interface is critical to long-term performance. The
design of the enclosure and the choice of gaskets must con-
sider the proper compression required for the gasket design.
Various gasket profiles are used to achieve the best possible
interface with the enclosure components. Equipto Electronics
utilizes multiple hinges and latch points on doors and multi-
ple compression points on panels in order to provide a bal-
anced pressure on the gasket material. R-3 and R-5 enclo-
sures utilize special door latches to provide proper gasket
compression and minimize closing force.
Beryllium copper spring-finger gasketing assures high shield-
ing integrity without requiring adjustment to compensate for a
compression set. When double gasketing is required, nick-
el/copper coated gasketing is added in the compression flange
of the frame.
Sag-Proof Doors
Because of the double ledge construction of all Equipto Electronics Door Latch
Enclosure frames, all doors are mounted extended from the frame
surface and recessed within the protective perimeter of the frame New leak-proof hinges and a triple camming, high pressure,
itself. All doors are mounted with heavy duty, separable, extruded one hand, easy operation, latching system prevent loss of
aluminum hinges having a 1/4” stainless steel pin and a nylon anti- shielding effectiveness. “Black Epoxy Finish”
friction bearing. This minimizes damage in shipping and allows
mounting of equipment directly on doors where required. Doors
are easily removable and Extended Doors allow room for protrud-
ing buttons and handles.
