M Series Connectors
Are lightweight triplestart ratchet coupling type connectors designed for avionics, aerospace, Harsh Environment Connectors, security, motorsport and heavy duty applications.
РусскийIn the demanding sectors of aerospace, defense, and industrial automation, the MIL-DTL-26482 Series I connector stands as a cornerstone for reliable, high-density interconnections. However, procurement teams often face challenges such as extended lead times, supply chain instability, or the need for cost-optimized alternatives that do not compromise on mission-critical performance. Finding a 1:1 equivalent that ensures full intermateability with industry standards like Amphenol PT, ITT Cannon KPT, or Souriau 851 is essential for maintaining production continuity.
RENHOTEC’s MS311x series is precision-engineered to meet the rigorous specifications of the MIL-DTL-26482 standard. These connectors are not just “similar”—they are designed to be intermateable, intermountable, and interchangeable with all compliant series from Tier-1 manufacturers. Whether you are looking for a drop-in replacement for a Wall Mount Receptacle (MS3110) or a Straight Plug (MS3116), our equivalents provide the same mechanical footprint and electrical integrity required for harsh environment applications.
MIL-DTL-26482 Series I vs. Series II: Deep Dive into Intermateability
For engineers and procurement specialists, understanding the distinction between Series I and Series II is critical to avoiding assembly failures. While both fall under the MIL-DTL-26482 umbrella, they are fundamentally different in design and are not intermateable.
The Mechanical Coupling System
The Series I (which includes the RENHOTEC MS311x, Amphenol PT, and ITT Cannon KPT) utilizes a 3-point quick-disconnect bayonet coupling system. This design allows for a positive tactile “click” when fully mated, ensuring the connection is secure even in high-vibration environments. To prevent cross-mating between different signal paths on the same panel, it employs a 5-keyway polarization system.
Key Differences: Series I vs. Series II
Intermateability: A Series I plug cannot mate with a Series II receptacle. The internal dimensions and contact retention mechanisms differ significantly.
Contact Termination: Series I is predominantly associated with solder contacts (though crimp versions exist), where contacts are permanently bonded into the synthetic rubber insulator. Series II typically utilizes rear-release crimp contacts.
Shell Design: Series I connectors, like the RENHOTEC MS311x, feature a more compact miniature circular metal shell design compared to some Series II equivalents.
Why Choose Series I Equivalents?
RENHOTEC Series I connectors are designed for 100% interchangeability with all MIL-DTL-26482 Series I compliant brands. This means a RENHOTEC MS3116 plug will mate perfectly with an existing Amphenol PT02 receptacle without any degradation in sealing or electrical performance.
Key Technical Specifications: Why High-Quality Equivalents Must Meet Military Standards?
In the context of mission-critical systems, an “equivalent” connector is more than just a dimensional match; it must replicate the material science and performance thresholds of the original MIL-DTL-26482 specifications. RENHOTEC MS311x series is engineered to withstand the exact environmental stressors that Amphenol or ITT components are rated for.
Superior Material Integrity
The reliability of a 26482 equivalent starts with its construction. RENHOTEC utilizes high-grade aluminum alloy for the shell, providing a rugged yet lightweight housing. The choice of synthetic rubber for the insulator and integrated rear wire sealing grommets is pivotal; it ensures a liquid-tight assembly and maintains insulation integrity even under thermal cycling. Furthermore, the use of copper alloy contacts with gold plating is not merely for conductivity, but to prevent oxidation and ensure stable contact resistance over the connector’s 500-cycle service life.
Performance Data Benchmark
The following table outlines the core technical parameters that any valid MIL-DTL-26482 Series I equivalent must achieve.
| Parameter | Specification Requirement | Benefit to Application |
| Operating Temperature | -55°C to +125°C | Ensures stable operation in both sub-zero aerospace and high-heat engine environments. |
| Water Pressure (Sealing) | 48 hours at 6 feet depth | Prevents ingress in maritime or outdoor industrial equipment (IP67+ equivalent). |
| Salt Spray Resistance | 48 hours (Standard Olive Drab) | Resists corrosion in coastal or saline-heavy industrial zones. |
| Insulation Resistance | 5,000 MΩ min at 500V DC | Prevents signal leakage and cross-talk in high-density contact arrangements. |
| Vibration Resistance | 10 to 2000Hz (15g) | Maintains electrical continuity (discontinuity <10µs) in high-vibration machinery. |
| Durability | 500 Mating Cycles | Guarantees long-term mechanical reliability for field-serviceable equipment. |
By adhering to these stringent benchmarks, our equivalents eliminate the risk of system failure when transitioning from Tier-1 brands. We verify these parameters in our internal labs to ensure every batch meets the technical requirements.
Core Cross-Reference Table: Amphenol PT, ITT KPT, and RENHOTEC Part Number Mapping
For procurement managers, the most critical step in sourcing an equivalent is ensuring the part numbers align across different manufacturers’ nomenclatures. The RENHOTEC MS311x series follows the military standard numbering, which maps directly to Amphenol’s PT/62IN series and ITT Cannon’s KPT series.
1:1 Interchangeability Mapping
The following table provides a high-level cross-reference for the most common shell styles. By utilizing these equivalents, teams can bypass long lead times associated with Tier-1 brands while maintaining identical form and fit.

How to Order: Decoding the 26482 Part Numbering System
Understanding the logic behind the code allows engineers to verify alternatives even for complex configurations. A typical RENHOTEC part number like MS3116F14-19PW breaks down as follows:
- Series (MS): Indicates Military Standard MIL-DTL-26482.
- Shell Style (3116): Defines the physical mounting (e.g., 3116 = Straight Plug).
- Service Class (F): Indicates environmental resistance with a strain relief clamp.
- Shell Size (14): The diameter of the connector housing.
- Insert Arrangement (19): Specifies the number and layout of contacts (in this case, 19 contacts).
- Contact Type (P): “P” for Pin (male) or “S” for Socket (female).
- Alternate Rotation (W): Prevents cross-mating by rotating the insert (Options: W, X, Y, Z).
Why RENHOTEC is the Ideal 26482 Connector Supply Chain Partner?
