M39029/56-348 Crimp Removable Contact, MIL-DTL-39029

The M39029/56-348 is a crimp removable contact manufactured to MIL-DTL-39029 specification. It is a removable pin or socket contact used inside compatible connector inserts (not a complete connector itself). Note: M39029 contacts are installed INTO compatible connector series such as MIL-DTL-38999 / GJB599, MIL-DTL-26482 Series 1 (MS3100/MS3102/MS3106), MIL-DTL-26482 Series 2 (62GB), MIL-DTL-27473 (MS27473), MIL-DTL-27484 (MS27484), MIL-DTL-27497 (MS27497), MIL-DTL-27508 (MS27508), and related insert configurations. The slash number (/56) and the part number suffix (348) define the contact size, gender (pin or socket), and plating — confirm exact meaning with supplier.

This contact features the /56 slash number (contact size/gauge — confirm exact size meaning with supplier) and the 348 suffix (pin/socket type and plating — confirm exact meaning with supplier). M39029 contacts are removable, crimp-terminated, and replaceable in the field using the appropriate insertion/extraction tooling.

Selection Guide

Installation Notes

• Verify slash number /56 (contact size/gauge) and suffix 348 (pin/socket type and plating) before installation. Confirm exact meanings with supplier.
• Use the correct crimp tool and locator for the M39029 /56 contact size (confirm tooling with supplier).
• Use the proper insertion/extraction tool to install or remove the contact from the connector insert without damaging the insert cavity.
• Ensure the connector insert arrangement accepts /56-size contacts before installation.
• M39029 contacts are NOT compatible with JY27656 (GJB), JY27466 (GJB), JY27496 (GJB), JY3470 (GJB), J30J series (GJB), J29A series (GJB), J36B series (GJB), 8D series, Y50 series, YLH series, ZH8525 series, YH3116 series, YW1 series, or SMA RF coaxial connector inserts unless confirmed by supplier — these series use their own contact standards.
• When mating, pair pin contacts with socket contacts of the same size/gauge inside the corresponding connector inserts.
