Our Y50 series circular connectors encompasses metric, imperial, and power connectors, meticulously engineered to meet the requirements of GJB101A—97, GJB598A—96, MIL-C-26482, and other industry standards. Our connectors are renowned for their swift connection and detachment, compact size, lightweight design, superior sealing performance, and exceptional tensile strength.

The Y50 series connectors offer seven installation methods for plug cable hoods, with both shielded and unshielded shell options available. Cable outlets include straight and angled configurations, while the termination method is welding.

The Y50 series connectors offer multiple variations and encompass exceptional features, including resistance to salt spray, moisture, and mold. They are specifically designed for applications in strategic and tactical systems, as well as field operations, enabling seamless transmission of electrical signals and power.
