31-Pin D-Type Hermetic Connector

PH08484-0000 - GlassTomer™ Sealed (Split Layout: 2 to 4 Rows)

A multi-pin connector combining an aluminum housing with GlassTomer™ hermetic sealing, with applications including vacuum electronics and rugged industrial systems.

Hermetron’s 31-pin D-type hermetic connector is engineered for high-density interconnects in harsh environments. This model features a split pin arrangement, evolving from a traditional 2-row configuration to a compact 4-row layout, enabling greater pin density without compromising reliability or performance.

This D-type hermetic connector is hermetically sealed using GlassTomer™ — an advanced glass-to-polymer compound providing superior sealing with excellent mechanical compliance. This ensures a reliable hermetic barrier in high-vacuum or pressure-differential environments.
