MS3102R18-11S Circular Connector, MIL-DTL-26482 Series 1 (MS3102)

The MS3102R18-11S is a circular electrical connector designed for aerospace, avionics, and industrial platforms. It conforms to MIL-DTL-26482 Series 1 (MS3102) requirements. Note: MIL-DTL-26482 Series 1 (MS3100/MS3102/MS3106) is a distinct standard, separate from 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), J30J 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 "R" style code (confirm exact meaning with supplier), shell size 18, insert arrangement 11 (contact layout — confirm with supplier), and socket contacts (S). The design supports threaded coupling and removable crimp contacts.

Compatible Applications

The MS3102R18-11S connector is intended for platforms that require MIL-DTL-26482 Series 1 (MS3102) compliant interconnects in shell size 18. Typical use cases include:

• Aircraft and helicopter wiring harness interconnects (MIL-DTL-26482 Series 1 standard)
• Ground vehicles and rugged electronic enclosures
• Industrial equipment requiring circular connectors
• Shipboard equipment requiring threaded coupling connectors
• Programs that standardize on MIL-DTL-26482 Series 1 (MS3102) interfaces

Selection Guide

Installation Notes

• Verify shell size 18, "R" style code, insert arrangement 11, and socket contacts before mating. Confirm the "R" style code meaning and arrangement 11 contact layout with supplier.
• Use the correct crimp tooling for the contact type specified by insert arrangement 11 (confirm contact size with supplier).
• Fully engage the threaded coupling with the mating connector until securely seated.
• Mate only with MIL-DTL-26482 Series 1 (MS3100/MS3102/MS3106) connectors of the same shell size 18, insert arrangement 11, and pin contacts.
• Do NOT attempt to mate with MIL-DTL-26482 Series 2 (62GB), MIL-DTL-27473, MIL-DTL-27484, D38999/J599 Series III, MS27497, MS27508, JY27466, JY3470, J29A, J30J, J36B, 8D, Y50, YLH, ZH8525, YH3116, YW1 series, or SMA RF coaxial connectors — MIL-DTL-26482 Series 1 is a different standard and is not interchangeable unless confirmed by supplier.
