Premium Durable M39029/56-348 22D# Socket Terminal for Electrical Applications

M39029/56-348 Electrical Contact, MIL-DTL-39029 Series

The M39029/56-348 is an electrical contact (removable crimp contact) designed for use in standard circular connectors. It conforms to MIL-DTL-39029 series requirements. Note: MIL-DTL-39029 contacts are used as internal contact elements within connectors conforming to standards such as MIL-DTL-38999 / GJB599, MIL-DTL-26482, MIL-DTL-27484, MIL-DTL-27497, and MIL-DTL-27508. The contact itself is not a standalone connector and is not directly form-fit-function interchangeable with complete connectors from any standard. Confirm exact contact size, wire gauge range, and compatible connector insert arrangements with supplier.

This contact features MIL-DTL-39029 specification, slash number /56 (contact type/design variant — confirm exact pin or socket type with supplier), and part number 348 (confirm exact contact size and wire gauge range with supplier). The design supports crimp termination for reliable wire-to-contact interconnection.
