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
