1. Product Overview

MS3116F18-32PN, a high-reliability high-density circular military connector supplied by KAIDA, is fully compliant with MIL-DTL-26482 Series I specifications. Designed as the dedicated mating plug for MS3112E18-32SN panel-mount receptacles, it enables simultaneous transmission of multiple signals and medium-power currents in harsh environments via 32 male pins (size #20). Featuring a rugged aluminum alloy shell, gold-plated conductive components, 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 aerospace applications requiring high-density, failure-resistant cable-to-equipment connections (e.g., complex sensor networks, multi-module control systems).

2. Core Electrical & Mechanical Parameters

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

3. Core Functional Features

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

4. Typical Application Scenarios

  1. Military & Aerospace:
    • Ground combat vehicles (cable connections for multi-sensor arrays—navigation, target detection, and communication modules—mating with MS3112E18-32SN-paneled ECUs);
    • Aircraft avionics (cabling for flight control auxiliary systems, e.g., pressure/temperature sensors, mating with MS3112-equipped instrument panels);
    • Naval vessels (cable assemblies for deck-mounted radar systems, resistant to saltwater corrosion and vibration).
  1. Industrial Automation:
    • Modular PLC systems (cabling for 32-channel I/O modules, connecting sensors/actuators to control cabinets with MS3112E18-32SN receptacles);
    • High-speed robotic arms (cable connections for joint position sensors, motor control signals, and power—reducing cable clutter via single connector);
    • Oil/gas field monitoring (cabling for downhole multi-parameter sensors—pressure, temperature, flow—mating with surface control units).
  1. Transportation:
    • Railway systems (cable connections for train carriage multi-sensor networks—door control, lighting, and passenger information—withstanding track vibration);
    • Electric vehicles (EVs) (cabling for battery management system (BMS) sensors, monitoring 32+ cell voltages via a single connector);
    • Marine equipment (cabling for shipboard navigation suites—GPS, sonar, and radio modules—IP67-sealed against seawater spray).
  1. Medical & Emergency Equipment:
    • Multi-parameter patient monitors (cable connections for ECG, SpO₂, blood pressure, and temperature sensors—mating with MS3112-paneled monitoring units);
