MS3116F14-19P Male Circular Connector, 19-Pin Plug, Bayonet Coupling, Military

Product Specification

1. Electrical Ratings:

• Rated Current: 7.5A per contact (consistent with #20 pin size, supporting medium-power transmission);

• Rated Voltage: 600V AC / 850V DC (typical), up to 1000V AC for short-duration operation;

• Contact Resistance: Maximum 4mΩ (gold plating minimizes signal loss and ensures low impedance);

• Insulation Resistance: Minimum 5000MΩ at 25℃ (prevents leakage current in high-voltage scenarios);

• Dielectric Withstand Voltage: 1500V AC (1 minute, no breakdown or arcing).

2. Mechanical Specifications:

• Contact Quantity: 19 male pins (size #20, mating with MS3112 receptacle’s female sockets for medium-density transmission);

• Termination Method: Crimp or solder (compatible with 20–24 AWG stranded wires for flexible cable assembly);

• Coupling Type: Bayonet lock (3-point self-levelling design, enabling tool-free, 1/4-turn mating with MS3112 receptacles);

• Mounting Style: Cable mount (designed for integration into power/signal cables, vs. MS3112’s panel-mount design);

• Mating Cycles: Minimum 500 (ensures long service life in frequently connected/disconnected cable systems);

• Insert Arrangement: Standard MIL-DTL-26482 pinout (100% compatible with MS3112 series receptacles of the same contact count).

3. Environmental Performance:

• Operating Temperature Range: -55℃ ~ 125℃ (adapts to polar, desert, and industrial high-temperature environments);

• Ingress Protection: IP67 (sealed against dust ingress and temporary submersion in 1m water for 30 minutes, after mating with MS3112 receptacle);

• Corrosion Resistance: Olive drab chromate over cadmium plating (passes 48+ hours of salt spray testing per MIL-STD-883);

• Vibration Resistance: Withstands 10–2000Hz, 10g acceleration (per MIL-STD-883 Method 2007, maintaining connection integrity);

• Shock Resistance: Survives 50g, 11ms half-sine shocks (per MIL-STD-883 Method 2002, no contact displacement).

4. Material & Dimensions:

• Shell Material: Aluminum alloy (lightweight yet high-strength, with anti-corrosion plating);

• Contact Material: Phosphor bronze (base) with 50µin gold plating (ensures conductivity and wear resistance after repeated mating);

• Insulator Material: Polychloroprene (oil-resistant, flame-retardant, meets UL94 V-0);

• Overall Dimensions: 28.5mm (length) × 26.3mm (diameter) (compact for integration into tight cable routing spaces).

1. Mating Compatibility with MS3112 Receptacles: Designed as the dedicated plug for MS3112 series panel-mount receptacles (e.g., MS3112E14-19S), ensuring seamless mechanical and electrical matching—eliminating compatibility issues in legacy military/industrial systems;

2. Cable-Mount Flexibility: Cable-mount design enables direct integration into power/signal cables (vs. panel-mount receptacles), simplifying cable-to-equipment connections in mobile devices (e.g., military radios, industrial sensors);

3. Quick & Secure Bayonet Coupling: 1/4-turn bayonet lock allows tool-free, fast mating/unmating, while the self-levelling mechanism compensates for minor cable misalignment—critical for field maintenance in harsh conditions;

4. Low Signal Degradation: Gold-plated pins (50µin thickness) maintain contact resistance <4mΩ even after 500 mating cycles, minimizing signal attenuation for high-frequency data transmission (e.g., industrial Ethernet, sensor networks);

5. Anti-Misinsertion Polarization: Five keyway positions on the shell align with MS3112 receptacles, preventing incorrect mating that could damage sensitive components (e.g., PLCs, avionics modules);

6. Military-Grade Durability: Compliance with MIL-DTL-26482 Series I ensures resistance to extreme stressors (vibration, corrosion, temperature swings)—suitable for mission-critical applications where failure is not tolerated.
