AIT/MS Series is a low cost, MIL-DTL-5015 (MIL-C-5015) threaded connector for use in harsh environmental conditions
The AIT/MS Series is a low‑cost, MIL‑DTL‑5015 (MIL‑C‑5015) threaded connector designed for harsh environments. It offers over 286 contact layouts, supporting 1 to 85 circuits and up to 150 A per contact, with options for solder, crimp, PC terminations, thermocouple and coax contacts. The rugged aluminum alloy shell and resilient neoprene insulator provide liquid‑tight sealing and resistance to moisture, vibration and flash‑over.
The document includes detailed technical specifications, electrical and mechanical data, and a step‑by‑step guide for constructing part numbers and ordering the connectors. It also lists approved materials, plating options, temperature limits, and performance test results for voltage, shock and vibration.
