You need premium power and signal connectors that combine reliability with power and efficiency. That’s where Combo-D connectors from Positronic come in. Our combo-D connectors provide the ultimate integration of power and signal in a single, compact connector. These connectors are designed to offer an all-encompassing solution for your power and signal connection needs, providing space-saving versatility, reliability, precision, and power even in the most demanding environments. What sets our Combo-D connector family apart from the competition? Let’s explore the details . . .

Combo-D Connectors: Standout Features

Versatility and Flexibility

Combo-D connectors offer an impressive range of mixed contact combinations with the ability to incorporate several contact types including:

• Power
• Shielded
• Radio Frequency
• High Voltage
• Thermocouple
• Signal

With over 20 connector variants across six standard shell sizes, you can rest assured there’s a layout engineered for your needs. An extensive array of mounting hardware, backshells, plating options, and locking systems are available to enhance flexibility, allowing for seamless integration into your system.

Space-Saving Design

Combo-D connectors pack their all-in-one versatility into a single, compact package. Not only does this revolutionary design feature save valuable space, but it also simplifies the all-important process of organizing and maintaining connections.

Power and Precision

Ideal for high-speed and high-frequency applications, Combo-D connectors come equipped with precision-machined Posiband signal contacts to ensure reliable transmission with minimal signal loss, even when performing in challenging environments where they might experience extreme temperatures, shocks, and vibrations.

For power-hungry applications, our female power contacts feature a generous surface area and closed entry design, effectively minimizing resistance and effortlessly handling up to 70 amperes. When high-speed data transfer is a must, our Twinax, Coax, and Fiber Optic contacts are available and ready to deliver exceptional performance.
