Spira’s NEW patent-pending EMI & Environmental Connector-Seal
gaskets are designed to provide an EMI & Environmental seal
in flange-mounted connectors for the life of a system. They provide
superior shielding quality and an excellent and durable environmental
seal. See below
for ordering information. Also note that Spira has EMI-only Connector-Seal gaskets.
Application Information
These gaskets are made by attaching a Spira-Shield O-Ring to
an environmental sealing retaining frame. The retaining frame
consists of a stainless steel plate with vulcanized silicone
or fluorosilicone sheeting on both sides of the plate. The stainless
steel plate eliminates cold flow of the environmental sealing
elastomer.
The EMI & Environmental Connector-Seal is designed primarily
for back mounting of the connector.
The shell sizes noted with an asterisk (*) can be used for both
front and back mounting.
Materials:
Frame: Corrosion resistant Stainless steel, between silicone
or fluorosilicone elastomeric sheeting material.
Spiral: Spira-Shield standard force tin/lead plated beryllium
copper gasket. Compression force is ~ 30 lbs/linear inch. (See
Options for RoHS compliance).
Refer to Material
Specifications for more information.
Shielding Quality:
Connector-Seal gaskets offer shielding quality from 116 to 152
dB. The level is dependent on contact surfaces and may vary depending
on your specific application. Refer to Shielding
Quality for more complete performance data.
Available Options
Plating:
The gasket is electroplated, 90% tin, 10% lead per AMS-P-81728
(edges unplated). Plating options can be specified by adding
a prefix before the part number:
E: Edge tin/lead plating (includes edges) for high humidity or
salt-fog environments
IW: RoHS compliant tin plating (Example: ECS-IW-21
/S)
EIW: RoHS compliant edge tin plating for high humidity or salt-fog
Refer to Material
Compatibility for more information.
Frame:
The frame is stainless steel sealed on both sides by silicone
or fluorosilicone elastomeric material. Specify “/S” for
Silicone or “/F” for Fluorosilicone.
The frame can also be ordered with the same dimensions but without
a shielding gasket by removing the “-T” from the
part number as shown in the table below.
