MIL-DTL-5516 Connectors are military-grade electrical connector designed for use in rugged environments. These connectors adhere to the specifications outlined in MIL-DTL-5516, which provide detailed requirements for audio frequency connectors used in military communication equipment. They are constructed to withstand harsh conditions, such as extreme temperatures, moisture, vibration, and shock, making them suitable for use in field and combat environments. 

MIL-DTL-55116 connectors 

MIL-DTL-5516 are miniature audio, five-pin and six-pin connectors primarily used for audio frequency signals, such as military radios, intercom signals, and other communication devices. The MIL-DTL-55116 specification gives detailed requirements for these connectors. It consists of design parameters, materials, performance criteria, and testing methodologies. The connectors must meet the standards to ensure compatibility and reliability across different military systems. They’re available in many configurations, including QPL, NSA, lightweight, and specialized/custom designs. They may be specified as in-line and panel-mount connectors, with EMI/RFI filtered receptacles.

Key Features of MIL-DTL-55116 Connectors

The structural design of MIL-DTL-55116 connectors is characterized by their circular form factor, and usually 5 to 6 pins or contacts for signal transmission. They’re constructed using high-quality materials such as rugged metal or insulating polymers that are engineered to withstand harsh environmental conditions and physical stress. The robust sealing mechanisms prevent the ingress of moisture and contaminants, which ensures long-term reliability and durability. Also, these connectors provide secure connections, reducing the risk of signal loss or interference.
