851 Hermetic Series Glass-Sealed Circular Connector | Eaton Souriau

Eaton Souriau 851 Hermetic Series is a compact, glass-sealed circular connector built for aerospace, military and industrial use. Its hermetic sealing delivers a very low leak rate, while the design is about 30% shorter than the standard version.

A quick 1/3-turn bayonet coupling ensures fast, secure mating. The series follows MIL-DTL-26482 Series I and is also available in HE301 and VG95328 configurations.

Built with steel shells, gold-plated contacts and fluorocarbon seals, it handles up to 17A and temperatures from -55°C to +125°C. Solder-cup contacts, multiple shell sizes and configurable layouts make it a flexible choice for harsh environments.
