MS3116 Series Circular Connectors: MIL-DTL-26482 Series I for Demanding Applications
Built to meet MIL-DTL-26482 Series I military specifications, the MS3116 series is a high-reliability circular connector engineered for critical applications where performance cannot be compromised—from aerospace and military vehicles to industrial automation and outdoor equipment. We offer the full range of MS3116 connectors, with multiple pin counts (2–61 contacts) available to match your system's exact needs.

Selecting the Right MS3116 Configuration
Choosing the correct connector starts with understanding your contact density, environmental exposure, and mating requirements. The MS3116 series supports both low-density signal setups and high-density power/signal integration, with contact diameters of 1.6mm and 2.3mm available across the lineup.
-
Contact count: 2 to 61 pins to match channel requirements
-
Contact diameter: 1.6mm or 2.3mm depending on current and density needs
-
Gender: Male or female configurations for plug and receptacle matching
-
Coupling: 3-pin bayonet lock for anti-mislocation, one-handed mating
Popular models include MS3116F14-19S (19-pin) for mid-range signal transmission, MS3116F18-32S (32-pin) for multi-channel systems, and MS3116F24-61S (61-pin) for high-density applications. Confirm your mating-side interface and pinout before ordering to ensure correct pairing.

Environmental and Mechanical Durability
The MS3116 series is designed for harsh operating environments. The aluminum alloy housing resists vibration, salt spray, and corrosion, while IP67 sealing provides protection against water and dust ingress. The operating temperature range of -55°C to +125°C supports outdoor, marine, and battlefield deployments.
For applications exposed to continuous vibration or thermal cycling, verify that the connector's mounting style and cable strain relief match your installation. The bayonet coupling delivers secure mating with 500+ mating cycles, reducing downtime during field maintenance and replacement.

Electrical Performance and Insulation
The MS3116 series maintains stable signal and power transmission under extreme conditions. Contact resistance is ≤2.5mΩ, rated voltage is 600V AC, and dielectric withstand is 1500V AC for 1 minute. PBT and epoxy insulation materials enhance electrical safety and long-term reliability.
When planning your electrical load, confirm that the contact diameter and pin count match your current requirements. For high-density configurations, verify derating curves and ambient temperature effects on performance.

Application Fit and Boundaries
The MS3116 series suits aerospace, military vehicles, industrial automation, and outdoor equipment where MIL-DTL-26482 Series I compliance is required. It is not intended for applications requiring higher IP ratings while unmated, nor for environments exceeding the specified temperature range without additional protection.
For applications needing different coupling styles or higher pin densities, consider related MIL-spec connector families. Confirm your cable outside diameter and conductor size to ensure proper termination and sealing.

Inquiry Checklist for Accurate Matching
To receive the correct MS3116 connector configuration, provide the following details with your inquiry:
- Mating-side requirement (plug or receptacle, male or female)
- Pin count and pinout or wiring diagram
- Cable outside diameter and conductor size
- Electrical load (current, voltage) and environment
- Mounting style (cable, panel, or flange) and order quantity
