Circular Connectors

1. Overview

Circular connectors are multi-pin electrical connectors with circular contact arrangements, designed for reliable signal/power transmission in harsh environments. They feature robust mechanical structures, environmental sealing, and high mating durability. These connectors are critical in aerospace, industrial automation, and medical equipment where vibration resistance and signal integrity are paramount.

2. Main Types & Functional Classification

TypeFunctional CharacteristicsApplication Examples
MIL-DTL-38999High-density, threaded coupling, EMI shieldingAerospace systems, military vehicles
USB Type-CReversible design, 10Gbps data rate, 100W power deliverySmartphones, laptops, PDAs
BNCBayonet locking, 2GHz frequency rangeTest equipment, video systems
LVDT CircularLinear variable differential transformer integrationIndustrial sensors, robotics

3. Structure & Components

Typical construction includes: - Shell: Aluminum alloy/zinc die-cast housing with corrosion-resistant plating - Contacts: Gold-plated phosphor bronze with 0.5-2.0mm diameter - Insulation: High-temperature thermoplastic (200 C rating) - Sealing: IP67/IP68 rated elastomer gaskets - Mounting: Threaded/flange/clamp mechanisms

4. Key Technical Parameters

ParameterTypical RangeImportance
Voltage Rating50V-600VDetermines power transmission capacity
Current Rating1A-25A/contactAffects thermal performance
Contact Resistance 5m Impacts signal integrity
IP RatingIP40-IP68Defines environmental protection level
Operating Temp-65 C to +200 CMaterial stability indicator
Mating Cycles500-10,000Service life predictor

5. Application Fields

  • Aerospace: Flight control systems, satellite antennas
  • Industrial: CNC machines, automated guided vehicles
  • Medical: MRI scanners, patient monitoring systems
  • Telecom: 5G base stations, fiber optic networks
  • Consumer: VR headsets, gaming peripherals

6. Leading Manufacturers

ManufacturerKey ProductsSpecial Features
AmphenolMIL-DTL-38999 seriesComposite materials, EMI filtering
TE ConnectivityDEUTSCH D38999Thermoplastic housing, 2000V dielectric
MolexUSB Type-C 10GbpsShielded twinax design
DelphiAutomotive circular connectorsIP69K rating for EV charging
LemoPush-pull circular seriesSubminiature, 5000+ mating cycles

7. Selection Guidelines

Key considerations: 1. Environmental factors: Temperature extremes, fluid exposure 2. Electrical requirements: Signal type (analog/digital), current load 3. Mechanical constraints: Panel space, mating force limitations 4. Compliance standards: MIL-STD, ISO 6722, RoHS 5. Cost vs. longevity: High-cycle applications justify premium connectors

8. Industry Trends

Emerging developments include: - Miniaturization: 1.0mm contact pitch enabling wearable devices - High-speed transmission: 25Gbps+ differential pairs for industrial IoT - Smart connectors: Integrated sensors for condition monitoring - Material innovation: Graphene-coated contacts reducing resistance - Eco-design: Halogen-free thermoplastics meeting REACH regulations
