Introduction
Product Overview
The Bel Cinch MD801 Series connectors are high-reliability circular connectors designed for demanding military and aerospace applications. Featuring a Dual-Start ACME thread for enhanced protection against cross-mating and vibration, these connectors offer full performance in extreme environments. They are available in various shell materials and finishes, with options for crimp, solder, or PC tail terminations. The MD801 Series is suitable for critical components and assemblies where preventing leakage under extreme temperature, pressure, and humidity changes is essential. Key markets include military, aerospace, and down-hole applications. These connectors provide a reduced size and weight compared to traditional MIL-DTL-38999 connectors.
