High-Performance J30J/J30 Series Mini-Rectangular Connectors - China Suppliers & Factory for Military Electronics
Features and Advantages
⚡
High-density, miniaturized connectors engineered to meet the rigorous demands of the GJB2446A military standard — delivering reliability, durability, and design flexibility.
-
1A core feature of this series is its high-density contact arrangement, available in two standard grid patterns: 1.27mm × 2.54mm and 2.54mm × 2.54mm.
-
2This configuration allows for a significantly high number of signal and power contacts within a compact footprint, directly supporting system miniaturization.
-
3The connectors utilize wire twisting pin (twisted-pin) contacts, a design that provides multiple, redundant points of electrical contact.
-
4This yields key advantages: superior electrical conductivity with low and stable contact resistance, excellent resilience against vibration and shock, and enhanced durability over numerous mating cycles.
-
5The series offers versatility in construction with both metal and plastic shell options.
-
6Metal shells provide robust EMI shielding and maximum mechanical strength, while plastic shells offer a lighter-weight alternative for applications where weight reduction is critical.
-
7This flexibility allows designers to optimize the connector for specific performance, weight, and cost targets without sacrificing the inherent reliability mandated by the GJB2446A standard.
Application
These connectors are widely used for electrical circuit connections in military electronic equipment. Their primary application is in systems where small installation space and light weight are non-negotiable design drivers.

Frequently Asked Questions
Q
What grid pitch options are available for this connector series?
This series is available in two standard high-density grid patterns: 1.27mm × 2.54mm and 2.54mm × 2.54mm. These configurations enable a high number of contacts within a minimal footprint, supporting compact system designs.
Q
What is a wire twisting pin contact, and why is it used?
A wire twisting pin (twisted-pin) contact is a design that creates multiple redundant points of electrical contact. This results in lower and more stable contact resistance, improved resistance to vibration and shock, and longer service life over repeated mating cycles — all critical for military-grade applications.
Q
What is the difference between metal shell and plastic shell connectors in this series?
Metal shell connectors offer robust EMI shielding and superior mechanical strength, making them ideal for harsh electromagnetic environments. Plastic shell connectors are lighter in weight, suited for weight-sensitive applications such as portable equipment and UAVs, while still meeting GJB2446A reliability requirements.
Q
Which military standard do these connectors comply with?
These connectors are designed and manufactured in compliance with the GJB2446A Chinese military standard, which governs performance, reliability, and environmental resistance requirements for military-grade rectangular electrical connectors.
Q
Are these connectors suitable for use in UAVs and avionics systems?
Yes. These connectors are well-suited for avionics and UAV applications including onboard mission computers, flight control systems, and sensor pods. Their compact footprint, light weight, and vibration-resistant twisted-pin contacts make them an excellent choice for airborne platforms.
Q
Can these connectors be used in both signal and power contact applications?
Yes. The high-density grid arrangement supports both signal and power contacts within the same compact connector body. This dual capability makes them highly versatile for complex military electronic systems that require both data transmission and power delivery in a single, space-saving interface.
