HD D-Sub 78 Pin Female Connector, Cable Type, Solder Cup, 2.29mm Pitch, Machined Contacts

Introduction:

This D-sub 78 pin female connector provides a high-density solution for complex I/O applications. It is engineered for cable mounting, featuring solder cup terminals for a secure, permanent connection of individual wires. This connector is built with high-quality machined contacts, offering superior durability and a more reliable connection than standard stamped types, which is critical for high pin count interfaces. Its gold-plated contacts ensure excellent signal integrity. With a rugged steel shell for protection, it’s an ideal choice for medical devices, industrial control systems, and specialized data communication equipment.

This D-sub 78 pin female connector has many great features, including:

  • High-Density: Offers a compact solution for applications requiring a high number of signal lines.
  • Solder Cup Termination: Allows for direct, secure soldering of individual wires for custom cable assemblies.
  • Machined Contacts: Provides superior durability and a more reliable connection for critical, high-mating-cycle use.
  • Cable Mount Design: Designed to be mounted directly on a cable, perfect for building custom I/O harnesses.
  • Gold-Plated Contacts: Ensures excellent conductivity and long-term corrosion resistance across all pins.
  • Durable Steel Shell: A strong nickel-plated housing offers robust physical protection and EMI shielding.
