Industrial control interconnects
Product Overview
The M39029/57-357 is a size 20 crimp socket contact manufactured to MIL-DTL-39029 standards. It is designed for use in high-reliability circular connector systems. Because stable electrical performance is critical in regulated assemblies, the contact is engineered for consistent conductivity and retention.
Moreover, the gold plating enhances durability while resisting oxidation over time. This makes the contact suitable for aerospace platforms, military vehicles, and industrial equipment exposed to vibration and temperature variation. In addition, compatibility with MIL-DTL-38999 and related connector series allows flexible integration into approved harness assemblies.
As a result, engineers rely on M39029/57-357 contacts when building durable and mission-critical interconnect systems. Cyndtek supplies new MIL-qualified components ready for immediate deployment.
