D-Sub Mixed Contact Connectors, High Power High Current

Introduction

​​D-Sub Mixed Contact Connectors (often called Hybrid D-Subs) are specialized versions of the classic D-subminiature connector designed to combine different types of electrical contacts within a single, shielded metal shell. Unlike standard D-subs carrying only signal pins, these hybrids integrate conventional signal contacts alongside larger, higher-current power contacts and/or specialized coaxial (RF) contacts. This key feature of mixing contact types solves the common problem of needing separate connectors for signals, power delivery, and high-frequency signals in space-constrained applications. Their primary advantage is significant space and weight savings on panels and PCBs, reduced cable complexity, and fewer potential points of failure. You'll commonly find them in industrial automation systems, test equipment, telecom gear, medical devices, and military/aerospace applications where consolidating functionality into one robust connector is critical.​​

Features

• Space & Weight Savings:​​ Integrating power/coax into one connector reduces the number of connectors needed on a panel or PCB.
• ​​Simplicity:​​ Reduces cable count and simplifies assembly.
• ​​Reduced Points of Failure:​​ Fewer connectors mean fewer potential failure points.
• ​​EMI Protection:​​ Leverages the inherent EMI shielding of the metal D-sub shell for all contacts.
• ​​Robustness:​​ Maintains the mechanical strength and mating security of standard D-subs.
• ​​Cost-Effectiveness (Sometimes):​​ While often more expensive than standard D-subs, using one hybrid connector can be cheaper than multiple separate connectors and cabling.

Types

Applications

1. ​​​​Industrial Automation:​​ Connecting PLCs to sensors/actuators needing both signal and power.
2. ​​Test & Measurement Equipment:​​ Providing signal, control, and power to devices under test.
3. ​​Telecom Equipment:​​ Combining data lines and power feeds.
4. ​​Military/Aerospace:​​ Weight-critical applications where functionality must be packed densely.
5. ​​Medical Devices:​​ Connecting monitors or probes that require both data and power.
6. ​​Broadcast/Video:​​ Combining control signals (RS-422/485) and RF outputs (e.g., legacy video equipment).
7. ​​Power-over-Data-Line Systems:​​ Some designs power devices over data pins.
