CX2-55 Long Type Glass Fused Vacuum Sealed ConnectorThe wall penetration thickness issue has been resolved. With technological advancements, the past panel thickness of 5mm was far from meeting the pressure resistance standards. Now, there is no longer a need for boring the panel, as the thickness of the panel itself has been increased from the original 3mm to 5mm. The interface dimensions remain unchanged, allowing for full compatibility with the original plug. The plug has distinct color coding inside and out—blue inside and red outside—making it easily identifiable at a glance, preventing incorrect insertion. Additionally, the lengthened size provides a comfortable grip and allows for smooth insertion and removal.
