MS27656T25B46S Description

Short technical summary and product information.

The MS27656T25B46S is a circular connector receptacle from Amphenol Aerospace Operations, part of the MIL-DTL-38999 Series I family. It offers 46 positions including 2 coaxial contacts in a female socket configuration, terminated via crimp for reliable wire connection. The connector features a bayonet lock fastening system for secure mating in high-vibration environments.

 

The shell is constructed from aluminum with an olive drab cadmium over nickel finish, providing corrosion resistance and durability. The contacts are gold-plated, ensuring low contact resistance and long-term reliability. Unshielded and rated for operating temperatures from -65°C to 175°C, this receptacle is designed for panel mount applications using a flange mounting feature.

 

Environment resistant construction allows use in harsh industrial, aerospace, and defense applications where exposure to moisture, dust, and extreme temperatures is expected. The connector is classified as RoHS3 compliant (unverified) and has a MSL of 1 (unlimited).

 

Typical applications include aircraft wiring systems, ground support equipment, and military electronic enclosures where high-density interconnect and field-proven robustness are required.
