Hermetic Connectors

Glass Sealed Hermetic Connectors

Users around the world have found that ITT Cannon hermetic connectors function reliably under extreme environmental conditions. Hermetic connectors are impervious to most liquids and gases, including acids, alkalis, oils, gasoline, jet fuel and hydraulic fluids. They can take shock loads as high as 100 g’s with no loss in hermeticity, and can take extremes of both heat and cold with no loss of performance.

Manufacturing Expertise

Cannon compression glass seals are strong. A 50,000
psi compression stress generates a sealing force that
can withstand up to 10,000 psi differential pressure
pressure varies with connector type . Since it is
independent of adhesion, the seal has a temperature
capability of -260° to +450° Fahrenheit. The seal has
high radiation resistance and a leak rate of less than
10-8 cc per second.

All ITT Cannon hermetic connectors are 100% tested after fabrication. A stringent examination ensures that all military specifications are met. The product is tested for leak performance, dielectric withstanding voltage and insulation resistance.

Glass is an ideal electrical insulating material for connectors. Its mechanical strength readily supports contacts. The compression seal is achieved by placing a glass preform within the surrounding metal shell, heating the glass and shell to the glass melting temperature, and then cooling the assembly.
