Description

D-SUB High Current Combo Connector

Reliable Power & Signal Transmission in a Compact D-Sub Form Factor

The D-SUB High Current Combo Connector combines high-current power contacts and standard signal pins in one compact, robust D-Sub housing. Designed for industrial, automation, communication, military electronics, and rugged embedded systems, this connector provides an efficient mixed-density interconnect solution where space, reliability, and performance matter.

Key Features

1. Mixed Power + Signal in One Connector

• Integrated layout of high-current pins (10A–40A depending on model) and standard D-Sub signal contacts

• Reduces the number of connectors required on the device panel

• Ideal for compact industrial equipment and control modules

2. High-Current Power Contacts

• Large-diameter machined power contacts

• Low contact resistance and optimized thermal performance

• Suitable for power distribution, motor drives, actuators, and embedded PSU interfaces

3. Industry-Standard D-Sub Construction

• Available in Type A / B / C / D / E shell sizes

• Standard footprints for easy PCB, panel, or cable integration

• Fully compatible with common D-Sub accessories and hardware

4. Multiple Insulator (Epoxy) Options

• White epoxy – Standard version, good insulation, cost-effective

• Black epoxy – Enhanced heat and chemical resistance

• Blue epoxy – High-visibility for quality inspection and differentiation
  (These do not affect electrical performance; mainly mechanical and environmental differences.)

5. Durable Housing & Shielding

• Metal shell for EMI/RFI shielding

• Optional waterproof or vibration-resistant versions

• Suitable for harsh industrial environments

6. Flexible Mounting Options

• Right-angle or straight PCB mount

• Panel mount with threaded inserts

• Cable assembly options available (upon request)
