1. Product Overview

MS3116F8-3S, a high-reliability low-density circular military connector supplied by KAIDA, fully complies with MIL-DTL-26482 Series I specifications. Designed as the dedicated mating plug for MS3112E8-3S panel-mount receptacles, it enables high-current power transmission and critical signal transfer in harsh environments via 3 male pins (size #16—larger than the #20 pins of high-density models). Featuring a rugged aluminum alloy shell, gold-plated high-conductivity contacts, and a cable-mount design, it integrates a quick-lock bayonet coupling system to maintain stable connectivity under extreme conditions—including intense vibration, wide temperature fluctuations, and chemical corrosion. This configuration makes it ideal for military, industrial, and transportation applications requiring low-density yet high-current, failure-resistant cable-to-equipment connections (e.g., power supplies for heavy-duty motors, critical control signals).

2. Core Electrical & Mechanical Parameters

  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).
  1. 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).
  1. 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).
  1. 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).

3. Core Functional Features

  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);
  1. 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;
  1. 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);
  1. 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);
  1. 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);
  1. 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.

4. Typical Application Scenarios

  1. Military & Aerospace:
    • Ground combat vehicles (power cable connections for heavy-duty motors—e.g., turret rotation, door actuators—mating with MS3112E8-3S-paneled power distribution units);
