Product Description

J30J-21TJS Circular Connector, J30J Series (GJB)

The J30J-21TJS is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It conforms to J30J (GJB) series requirements. Note: J30J series (GJB) is a distinct standard, separate from MIL-DTL-26482 Series 1 (MS3100/MS3102/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), J29A series (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 21, "TJS" style code (connector type/design variant — confirm exact meaning with supplier), and socket contacts (S). The design supports EMI shielding and removable crimp contacts.

Installation Notes

Verify shell size 21, "TJS" style code, and socket contacts before mating. Confirm the "TJS" style code meaning with supplier.
Use the correct crimp tooling for the J30J contact type (confirm contact size with supplier).
Fully engage the coupling with the mating connector until securely seated.
Mate only with J30J (GJB) connectors of the same shell size 21 and pin contacts.
Do NOT attempt to mate with MIL-DTL-26482 Series 1 & 2 (62GB), MIL-DTL-27473, MIL-DTL-27484, D38999/J599 Series III, MS27497, MS27508, JY27466, JY3470, J29A, 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.
