MS3116F8-3S 3-Pin Male Circular Connector, Bayonet Lock, Heavy-Duty, Vibration

Product Specification

1. Electrical Ratings:

• Rated Current: 13A per contact (consistent with #16 pin size, supporting high-power transmission—vs. 7.5A of #20 pins in high-density models);

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

• Contact Resistance: Maximum 3mΩ (lower than high-density models, minimizing power loss during high-current transmission);

• Insulation Resistance: Minimum 5000MΩ at 25℃ (prevents leakage current in power-focused applications);

• Dielectric Withstand Voltage: 1800V AC (1 minute, higher than high-density models to ensure safety in high-power scenarios).

2. Mechanical Specifications:

• Contact Quantity: 3 male pins (size #16, mating with MS3112E8-3S’s female sockets for low-density power/signal integration);

• Termination Method: Crimp or solder (compatible with 16–20 AWG stranded wires—thicker than high-density models to match high-current needs);

• Coupling Type: Bayonet lock (3-point self-levelling design, tool-free 1/4-turn mating with MS3112E8-3S receptacles);

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

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

• Insert Arrangement: Standard MIL-DTL-26482 pinout (100% compatibility with MS3112E8-3S receptacles, no reengineering for legacy setups).

3. Environmental Performance:

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

• Ingress Protection: IP67 (sealed against dust and 1m temporary submersion, after mating with MS3112E8-3S);

• Corrosion Resistance: Olive drab chromate over cadmium plating (passes 72+ hours of salt spray testing per MIL-STD-883—longer than high-density models for power-focused outdoor use);

• Vibration Resistance: Withstands 10–2000Hz, 15g acceleration (per MIL-STD-883 Method 2007—higher tolerance than high-density models for power equipment vibration);

• Shock Resistance: Survives 75g, 11ms half-sine shocks (per MIL-STD-883 Method 2002—enhanced protection for power cable impact).

4. Material & Dimensions:

• Shell Material: Thickened aluminum alloy (1.2mm wall vs. 0.8mm of high-density models, improving mechanical strength for power cable use);

• Contact Material: Phosphor bronze (base) with 75µin gold plating (thicker than high-density models’ 50µin, ensuring high conductivity and wear resistance under high current);

• Insulator Material: Heat-resistant polychloroprene (meets UL94 V-0, withstands 150℃ short-term heat—suitable for power dissipation);

• Overall Dimensions: 26.0mm (length) × 22.5mm (diameter) (compact for low-density installations, smaller than 32-pin models).

1. High-Current Low-Density Transmission: 3 #16 pins (13A each) enable focused high-power delivery (e.g., 24V/36W single-channel or dual-channel power + 1 signal) — ideal for applications where multi-signal density is unnecessary but current capacity is critical (vs. 32-pin models’ multi-signal focus);

2. Dedicated Mating with MS3112E8-3S: Engineered as the exact plug counterpart for MS3112E8-3S panel-mount receptacles, ensuring seamless mechanical alignment and electrical matching—eliminating power mismatch risks in mission-critical systems;

3. Power-Optimized Design: Thicker #16 pins, 75µin gold plating, and 16–20 AWG wire compatibility minimize power loss (<3mΩ contact resistance), critical for battery-powered or remote equipment (e.g., military field generators);

4. Fast Power System Maintenance: 1/4-turn bayonet lock enables tool-free mating/unmating—critical for quick power cable replacement in harsh field conditions (e.g., construction sites, battlefield power units);

5. Enhanced Environmental Durability: 72-hour salt spray resistance, 15g vibration tolerance, and 150℃ heat-resistant insulation exceed high-density models’ specs, suitable for outdoor power equipment (e.g., solar inverters, industrial motors);

6. Military-Grade Safety: 1800V AC dielectric withstand voltage and low leakage current (≥5000MΩ insulation resistance) ensure safe operation in high-power military/industrial systems—preventing short circuits or electric shock.
