China J30JM1/2 Series Gas Sealed Mini-Rectangular Connectors - Reliable Suppliers and Factory Solutions
Features and Advantages
-
1
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.
-
2
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.
-
3
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.
