J30J-25ZKN Circular Connector, J30J Series (GJB)
The J30J-25ZKN is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It conforms to J30J (GJB) series requirements. Note: J30J is a distinct standard, separate from MIL-DTL-26482 Series 1 (MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-38999 / GJB599, MIL-DTL-27473 (MS27473), MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), JY27466 (GJB), JY3470 (GJB), J36B series (GJB), 8D series, Y50 series, YLH series, ZH8525 series, YH3116 series, YW1 series, and SMA RF coaxial connectors, and is not directly form-fit-function interchangeable with any of those connectors unless confirmed by the supplier.
This connector features shell size 25, "ZK" style code (connector type/design variant — confirm exact meaning with supplier), normal keying (N), and contact gender not explicitly designated in the part number (confirm with supplier). The design supports EMI shielding, threaded coupling, and removable crimp contacts.

Installation Notes
- Verify shell size 25, "ZK" style code, contact gender, and normal keying before mating. Confirm the "ZK" style code meaning, insert arrangement, and contact gender with supplier.
- Use the correct crimp tooling for the contact type specified by the insert arrangement (confirm contact size with supplier).
- Fully engage the threaded coupling with the mating J30J connector until securely seated.
- Mate only with J30J (GJB) connectors of the same shell size 25, "ZK" style, normal keying, and opposite contact gender.
- Do NOT attempt to mate with MIL-DTL-26482 Series 1 (MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-27473, MIL-DTL-27484, D38999/J599 Series III, MS27497, MS27508, JY27466, JY3470, J36B, 8D, Y50, YLH, ZH8525, YH3116, YW1 series, or SMA RF coaxial connectors — J30J is a different standard and is not interchangeable unless confirmed by supplier.
