Circular Connectors - Housings

1. Overview

Circular connectors housings are electromechanical devices designed to protect and organize electrical contacts in circular configurations. They serve as mechanical support structures while providing environmental protection, electrical insulation, and strain relief. These housings are critical components in maintaining signal integrity and power transmission across diverse applications, from industrial automation to aerospace systems.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Metal Housings	High durability, EMI/RFI shielding, vibration resistance	Military equipment, aerospace systems
Plastic Housings	Lightweight, corrosion-resistant, cost-effective	Consumer electronics, medical devices
Hybrid Housings	Combination of metal/plastic for optimized performance	Automotive sensors, industrial machinery
High-Density Housings	Miniaturized contact arrangements with advanced insulation	Telecom equipment, data centers

3. Structure and Components

Typical circular connector housings consist of: - Shell Body: Cylindrical main structure (metal/plastic) with mounting threads - Contact Cavities: Precision-machined compartments for terminal placement - Sealing System: Integrated gaskets/O-rings for IP65+ protection - Polarization Key: Mechanical feature preventing misalignment - Retention System: Threaded coupling or bayonet mechanisms - Cable Entry: Strain relief provisions with gland seals

4. Key Technical Specifications

Parameter	Importance
Current Rating (A)	Determines power transmission capacity
Voltage Withstand (V)	Ensures dielectric strength
Operating Temperature (-40 C to +125 C)	Defines environmental tolerance
Vibration Resistance (10-2000Hz)	Crucial for harsh environments
IP Rating (IP67/IP68)	Specifies ingress protection level
Contact Retention Force	Prevents accidental disconnection

5. Application Fields

Industrial Automation: Robotics, PLC systems
Medical Equipment: MRI machines, patient monitoring systems
Aerospace: Avionics, flight control systems
Telecommunications: 5G base stations, fiber optic equipment
Energy: Wind turbines, solar inverters

6. Leading Manufacturers and Products

Manufacturer	Representative Product
