MS3116F18-32PN Military-Spec Circular Plug, 32 Contacts, Aluminum Shell,

Product Specification

1. Electrical Ratings:

• Rated Current: 7.5A per contact (consistent with #20 pin size, supporting parallel medium-power transmission for 32 channels);

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

• Contact Resistance: Maximum 4mΩ (gold plating minimizes signal loss, critical for high-density multi-signal transmission);

• Insulation Resistance: Minimum 5000MΩ at 25℃ (prevents cross-channel leakage current in high-density pin layouts);

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

2. Mechanical Specifications:

• Contact Quantity: 32 male pins (size #20, mating with MS3112E18-32SN’s female sockets for high-density signal/power integration);

• Termination Method: Crimp or solder (compatible with 20–24 AWG stranded wires, enabling flexible cable assembly for multi-channel systems);

• Coupling Type: Bayonet lock (3-point self-levelling design, tool-free 1/4-turn mating with MS3112E18-32SN receptacles);

• Mounting Style: Cable mount (optimized for integration into multi-conductor cables, vs. MS3112’s panel-mount design);

• Mating Cycles: Minimum 500 (ensures long service life in frequently reconfigured systems, e.g., modular industrial equipment);

• Insert Arrangement: Standard MIL-DTL-26482 pinout (100% compatibility with MS3112E18-32SN receptacles, no reengineering required for legacy systems).

3. Environmental Performance:

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

• Ingress Protection: IP67 (sealed against dust and 1m temporary submersion, after mating with MS3112E18-32SN);

• Corrosion Resistance: Olive drab chromate over cadmium plating (passes 48+ hours of salt spray testing per MIL-STD-883, suitable for marine/coastal applications);

• Vibration Resistance: Withstands 10–2000Hz, 10g acceleration (per MIL-STD-883 Method 2007, no contact displacement in mobile equipment);

• Shock Resistance: Survives 50g, 11ms half-sine shocks (per MIL-STD-883 Method 2002, protects against impact during field deployment).

4. Material & Dimensions:

• Shell Material: Aluminum alloy (lightweight yet high-strength, balances durability and cable routing flexibility);

• Contact Material: Phosphor bronze (base) with 50µin gold plating (ensures conductivity and wear resistance after 500+ mating cycles);

• Insulator Material: Polychloroprene (oil-resistant, flame-retardant, meets UL94 V-0, prevents pin-to-pin short circuits);

• Overall Dimensions: 32.0mm (length) × 30.5mm (diameter) (compact for high-density cable assemblies in tight enclosures).

1. 32-Channel High-Density Transmission: 32 integrated #20 pins enable simultaneous transmission of 32 independent signals (e.g., sensor data, control commands) or combined signal/power channels—reducing the number of connectors needed in complex systems by 40%+ compared to 19-pin models (e.g., MS3116F14-19P);

2. Dedicated Mating with MS3112E18-32SN: Engineered as the exact plug counterpart for MS3112E18-32SN receptacles, ensuring seamless mechanical alignment and electrical matching—eliminating compatibility risks in mission-critical systems;

3. Cable-Mount Versatility: Cable-mount design integrates directly into multi-conductor cables, simplifying connections between mobile devices (e.g., military radios, robotic arms) and panel-mounted equipment (e.g., control cabinets, ECUs);

4. Fast Field Maintenance: 1/4-turn bayonet lock enables tool-free mating/unmating, while the self-levelling mechanism compensates for cable misalignment—critical for quick repairs in harsh field conditions (e.g., battlefield, construction sites);

5. Low Cross-Channel Interference: Gold-plated contacts (50µin) maintain contact resistance <4mΩ, and the insulated pin layout minimizes crosstalk between adjacent channels—essential for high-frequency data transmission (e.g., industrial Ethernet, 485 bus);

6. Military-Grade Robustness: Compliance with MIL-DTL-26482 Series I ensures resistance to extreme stressors (vibration, corrosion, temperature swings)—suitable for applications where downtime is unacceptable (e.g., aerospace avionics, emergency medical equipment).
