China J30JM1/2 Series Gas Sealed Mini-Rectangular Connector - Reliable Factory Supply for High-Reliability Applications
Features and Advantages
-
🔒Hermetic Gas-Sealed Receptacle: The core feature is the gas-sealed receptacle, which utilizes a glass-to-metal sealing process. This creates a permanent, hermetic barrier that prevents gas or moisture ingress, ensuring long-term reliability.
-
📐High-Density Compact Layout: The connector boasts a high-density layout with a 1.27mm contact spacing and 1.1mm line spacing, allowing for a significant number of signal paths in a minimal footprint, contributing to its small volume and light weight.
-
⚡Flexible Wire-Twisted Pins: The plug employs flexible wire-twisted pins, which offer excellent shock and vibration resistance by absorbing mechanical stress and maintaining multiple contact points. This design, paired with an adaptive wire cross-sectional area of 0.05mm² to 0.15mm², ensures a reliable connection with stable electrical characteristics.
-
🛡️EMI/RFI Shielding & Customizable Housing: The housing's shielding provides inherent anti-interference (EMI/RFI) protection. An additional advantage is the customizability of shell size and installation method, allowing for perfect integration into specific system designs.
Application
These connectors are mainly used for critical electrical signal connections within hermetically sealed containers across advanced technological fields. Their primary applications include:
Sealed avionics modules, missile guidance systems, and sensor packages.
Electrical feedthroughs for scientific instruments, semiconductor processing equipment, and downhole tools.
Providing reliable external connections for implantable medical electronics.
Sealed housings for environmental sensors, deep-sea exploration equipment, and navigation systems.
Frequently Asked Questions
The glass-to-metal sealing process creates a permanent hermetic bond between the glass insulator and the metal shell. This barrier completely prevents gas or moisture from entering the connector, which is critical for maintaining long-term reliability in harsh or sealed environments.
These connectors support an adaptive wire cross-sectional area ranging from 0.05mm² to 0.15mm², making them suitable for fine-wire applications commonly found in precision electronics and miniaturized systems.
