1. Product Overview

MS3112E18-32SN, a high-reliability circular connector supplied by KAIDA, fully complies with MIL-DTL-26482 Series I military specifications—designed specifically for high-density signal and power transmission in harsh environments. As a box-mount receptacle equipped with 32 female socket contacts (size #20), it integrates rugged aluminum alloy housing, gold-plated conductive components, and a secure bayonet coupling system. This configuration enables stable connectivity even under extreme conditions such as intense vibration, wide temperature fluctuations, and chemical corrosion, making it suitable for military, industrial, and aerospace applications requiring high-density, failure-resistant connections.

2. Core Electrical & Mechanical Parameters

  1. Electrical Ratings:
    • Rated Current: 7.5A per contact (consistent with #20 contact 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).
  1. Mechanical Specifications:
    • Contact Quantity: 32 female sockets (size #20, enabling high-density signal/power integration);
    • Termination Method: Solder cup or crimp (compatible with 20–24 AWG stranded wires for flexible installation);
    • Coupling Type: Bayonet lock (3-point self-levelling design, enabling tool-free, 1/4-turn mating/unmating);
    • Mounting Style: Box/panel mount (flange design for secure attachment to enclosures);
    • Mating Cycles: Minimum 500 (ensures long service life in frequently connected/disconnected systems);
    • Insert Arrangement: Standard MIL-DTL-26482 pinout (compatible with mating plugs of the same series).
  1. 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);
    • 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);
    • Shock Resistance: Survives 50g, 11ms half-sine shocks (per MIL-STD-883 Method 2002).
  1. 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);
    • Insulator Material: Polychloroprene (oil-resistant, flame-retardant, meets UL94 V-0);
    • Overall Dimensions: 31.2mm (length) × 35.6mm (width) × 35.6mm (height) (compact for high-density PCB/enclosure layouts).

3. Core Functional Features

  1. High-Density Connectivity: 32 integrated contacts (vs. 19 in MS3112E14-19S) enable simultaneous transmission of multiple signals (e.g., data, control) and medium-power currents, reducing the number of connectors needed in complex systems by 40%+;
  1. Military-Grade Durability: Compliance with MIL-DTL-26482 Series I ensures resistance to extreme environmental stressors—critical for mission-critical equipment (e.g., military ground vehicles, aerospace auxiliary systems);
  1. Quick & Secure Coupling: Bayonet lock design allows fast mating (1/4-turn) without tools, while the self-levelling mechanism compensates for minor alignment errors, preventing contact damage during installation;
  1. Low Signal Degradation: Gold-plated contacts (50µin thickness) maintain low contact resistance (<4mΩ) even after 500 mating cycles, minimizing signal attenuation for high-frequency data transmission (e.g., industrial Ethernet, sensor networks);
  1. Anti-Misinsertion Polarization: Five keyway positions on the shell ensure precise alignment with mating plugs, eliminating incorrect connections that could damage sensitive downstream components (e.g., PLCs, ADCs);
  1. Broad Compatibility: Standard MIL-DTL-26482 pinout and mechanical design enable seamless replacement of legacy connectors in existing military/industrial systems, reducing retrofitting costs.

4. Typical Application Scenarios

  1. Military & Aerospace:
    • Ground combat vehicles (power distribution, sensor data transmission for navigation/weapons systems);
    • Aircraft auxiliary systems (cabin lighting, communication modules, and avionics sensor networks);
    • Naval equipment (submarine or surface vessel electronics, resistant to saltwater corrosion).
  1. Industrial Automation:
    • Complex PLC systems (connecting multiple I/O modules, motor drives, and human-machine interfaces);
    • Factory automation networks (high-density signal transmission for robotic arms, vision inspection systems);
    • Oil/gas field instrumentation (sealed connections for downhole sensors, pipeline monitoring devices).
  1. Transportation:
    • Railway systems (train control units, passenger information systems, resistant to vibration and temperature swings);
    • Marine vessels (shipboard power distribution, navigation equipment, IP67-sealed for deck-mounted use);
    • Heavy-duty trucks (telematics modules, engine control sensors, durable against road debris and moisture).
  1. Medical & Emergency Equipment:
    • Portable medical devices (multi-parameter patient monitors, connecting ECG, SpO₂, and temperature sensors);
    • Emergency response vehicles (ambulance life support systems, secure power/signal connections during transit);
    • Industrial-grade medical imaging equipment (CT scanner auxiliary components, low-noise signal transmission).
  1. Outdoor & Ruggedized Electronics:
    • Environmental monitoring stations (weather sensors, seismic detectors, IP67-sealed for outdoor use);
    • Ruggedized tablets/laptops (military field use, connecting peripherals like barcode scanners and GPS modules);
    • Renewable energy systems (solar inverter sensors, wind turbine control units, resistant to extreme temperatures).
