Defense Electronics Enclosure Sealing

Safeguarding Critical Electronics

Critical navigation, positioning and measurement electronics used in aerospace and defense equipment are becoming increasingly more powerful, as well as smaller, lighter, and more easily serviceable in the field. The fact that mission critical units are deployed the world over on vehicles, manned and unmanned aircraft and carried by personnel means that sealing capabilities of aerospace and defense electronics enclosures must encompass a wide range of handling, operating conditions, and climates.

Stringent no-fail static seal performance requirements include but are not limited to fluid compatibility, extreme operational conditions and environmental stresses, EMI shielding, and easy in-field serviceability.

Rugged Environmental Sealing Protection

For environmentally-sealed and EMI-shielded electronics devices, there is no better full-system solution than an overmolded cover. And with Parker, customers have access to a wide range of qualified, high performance elastomer materials including most Parker O-Ring compounds.

Overmolding is the process of molding a gasket directly onto a metal or composite substrate. Instead of extruded cord stock, press-in-place, or molded sheets, the elastomer gasket is bonded directly onto the housing, box, or enclosure, and will retain its shape after molding.

Top benefits of using overmolded technology for enclosures include:

Integration and permanent adhesion
Simplification of assembly
Ease of maintenance and repair
Tighter tolerance controls
Smaller form factors and custom geometries
Consolidated supply chain

Electronics and Instrument Enclosure Applications

Enclosures provide static sealing protection for electrical, electronic, or mechanical components and instruments where typical functional performance requirements may include:

Fluid management: containment, exclusion, flow channeling
Contaminant exclusion
Thermal management & EMI shielding

Commercial & Defense Inertial Measurement Unit (IMU)

Dependable sealing of enclosures that safeguard IMU's is critical for delivering highly reliable measurements in changing environments such as robotics, stabilization, and pointing applications.

Micro-Electro-Mechanical Systems (MEMS) in Transportation, Industrial Equipment, Robotics

Micro-electro-mechanical system (MEMs) based inertial measurement units (IMU). Miniaturization, remote data interface across various markets including ag, AUVs, industrial equipment, robotics, survey/mapping, stabilization, drone.

Vertical Reference Units (VRU)

Also known as Attitude Reference (AR) Units, this sensor is an example of non-military applications involving roll damping, terrain compensation, and transformation between coordinate systems on platforms.

Navigation Electronics (GNSS/INS)

Sophisticated electronics typically associated with classified and mission critical navigation tasks requiring consistent precision for robotic, manned, and unmanned systems providing centimeter-level accuracy.
