MIL-Spec MS3116 Circular Connector with Bayonet Lock

MS3116 Connectors

MS3116 Circular Connector Overview

The MIL-Spec MS3116 circular connector is a high-reliability plug designed in accordance with MIL-DTL-26482 standards. Known for its rugged construction and stable electrical performance, the MS3116 connector is widely used in demanding environments where secure signal or power transmission is essential.

Featuring a robust die-cast aluminum alloy housing, the connector offers excellent mechanical strength while maintaining a lightweight structure. Its bayonet coupling mechanism ensures fast and secure mating, making installation simple while maintaining strong resistance to vibration and mechanical shock.

Because of these advantages, MS3116 connectors are commonly applied in aerospace systems, military equipment, communication devices, and industrial control applications.

Durable Aluminum Alloy Die-Cast Housing

One of the most important features of the MS3116 connector is its die-cast aluminum alloy shell. This housing material provides several key benefits:

• High mechanical strength and durability
• Excellent corrosion resistance
• Lightweight structure for easy integration
• Reliable performance in harsh environments

The aluminum alloy shell also helps protect internal contacts from physical damage and environmental factors. This makes the MS3116 connector suitable for applications that require long service life and consistent electrical performance.

Secure Bayonet Coupling Locking System

The bayonet coupling locking system is a defining feature of the MS3116 connector. Compared with threaded connectors, bayonet coupling allows faster connection and disconnection while still providing strong mechanical stability.

Key advantages include:

• Quick and convenient mating
• Strong resistance to vibration and shock
• Secure locking for stable electrical contact
• Reduced installation time during maintenance

This locking mechanism is particularly valuable in aerospace and military equipment where reliability and speed of maintenance are critical.

Stable Electrical Performance

MS3116 connectors are designed to deliver stable electrical conductivity and signal transmission even under demanding operating conditions. The internal contact system ensures consistent electrical connection and minimizes signal loss.

Typical electrical features include:

• Low contact resistance
• High insulation resistance
• Reliable voltage and current performance
• Stable signal transmission in complex environments

These characteristics make the connector suitable for both power transmission and signal applications, including communication systems, control circuits, and instrumentation.

Wide Range of Industrial Applications

Due to their durability and reliability, MS3116 connectors are widely used across multiple industries. Common applications include:

• Aerospace electrical systems
• Military communication equipment
• Industrial automation machinery
• Control and instrumentation systems
• Transportation and heavy equipment

Their ability to perform reliably in high-vibration and harsh environments makes them an ideal choice for mission-critical electrical connections.

Easy Installation and Maintenance

Another advantage of MS3116 connectors is their user-friendly design. The bayonet coupling system allows technicians to quickly connect or disconnect the plug without specialized tools.

This simplifies maintenance procedures and reduces equipment downtime. The robust housing and secure contact structure also help extend service life and minimize replacement frequency.

Selection Considerations and Inquiry Checklist

When selecting an MS3116 connector for your application, confirm the following details to ensure correct mating and performance:

• Mating connector series and shell size required
• Pin count and contact arrangement (2-61 pins available)
• Cable outside diameter and conductor size for termination
• Electrical load requirements (current and voltage)
• Operating environment and required ingress protection
• Order quantity and delivery schedule
