D-Sub, D-Shaped Connectors - Contacts: Precision Connectivity Solutions

Definition:
D-Sub, D-Shaped Connectors - Contacts are the essential conductive components within D-Sub connectors, designed to establish reliable electrical connections in a wide range of applications. These contacts, typically made from high-conductivity materials like copper alloys, are precision-engineered to ensure optimal signal transmission and mechanical durability. They are integral to the assembly of D-Sub connectors, which are widely recognized for their distinctive D-shaped metal shield and versatility in both analog and digital systems.

Types of Products in This Category:
This category includes a variety of contact types tailored to specific connector configurations and performance requirements:
- Male (Pin) Contacts: Designed to insert into corresponding female sockets, commonly used in plug connectors.
- Female (Socket) Contacts: Engineered to receive male pins, typically found in receptacle connectors.
- Crimp Contacts: For secure wire termination, offering high pull-out resistance and ease of installation.
- Solder Contacts: Provide a permanent, robust connection for PCB-mounted applications.
- High-Current Contacts: Built with thicker gauges to handle elevated power loads.
Materials may feature gold or tin plating to enhance conductivity and corrosion resistance.

Purchasing Recommendations:
When selecting D-Sub contacts, consider the following criteria to ensure compatibility and performance:
1. Contact Gender & Size: Match pin/socket types and size (e.g., 20-24 AWG for standard contacts) to your connector housing.
2. Plating Material: Gold plating excels in high-frequency/low-voltage applications, while tin suits cost-effective, high-durability needs.
3. Termination Method: Crimp contacts require proper tooling; solder contacts demand PCB compatibility.
4. Current Rating: Verify ampacity aligns with your system s power requirements.
5. Compliance Standards: Opt for MIL-DTL-24308 or IEC 60603-2 compliant products for rigorous environments.

For bulk procurement, prioritize suppliers offering customization (e.g., custom plating or lengths) and batch testing certifications to guarantee consistency in high-volume deployments.

Note: This classification targets engineers sourcing replacement parts or designing D-Sub assemblies, emphasizing interoperability and long-term reliability.
