Hybrid connectors

Fischer Connectors offers compact hybrid connectors that combine power, data, fluidic, and optical connections into a single interface, ensuring accurate and error-free establishment of connections in compact devices.


Today’s devices are more complex, often requiring connections involving a combination of power and data contacts, as well as the use of fluids (such as helium or compressed air), optical fibers. It is crucial that each of these connections is accurately established every time without any room for error or misconnection, which may lead to safety issues, time delays, and damaged equipment. In environments where quick actions are vital, such as the medical field, limiting the number of connections saves time and facilitates device installation.


Fischer Connectors has developed several types of solutions that combine such critical connections into one single, small, multi-tasking connector and cable. These so-called hybrid connectors simplify user interface and connect multiple electrical, fluidic and/or optical lines with just one touch.

Examples of high-performance hybrid connector applications


Power and data

The integration of power and data into a single connector allows operators to establish secure and reliable connections in one move, facilitating device installation and handling, while limiting the number of connections. These hybrid connectors with mixed contacts give engineers the freedom to design sleeker and more compact devices by optimizing space utilization and enhancing overall functionality, while withstanding the rigorous demands of extreme environments: instrumentation, UAV applications, medical equipment, defense, IOT…


Power and fluid for medical devices

Medical practitioners work with complex connected devices requiring fluids, power and data in devices that are sterilized in the autoclave, manipulated multiple times, resist shock and vibration, and must cope with long lifecycles:

  • Medical pneumatic devices/instruments with compressed air supply (or other fluids) for puncturing, drilling, sawing, shockwave, etc.
  • Therapeutic (pain therapy, rehabilitation) using shock wave or for surgical handpieces and devices (urology surgery, dental surgery)

Power and fluid for test and measurement

For test and measurement applications, hybrid connectors with gas or liquid and low-voltage connections offer a flexible solution, enabling effective and precise testing and monitoring.


The helium and hydrogen sniffer leak detector from Pfeiffer Vacuum stands for high sensitivity (10-7 mbar l/s), accuracy and repeatability in industrial applications like refrigeration, air conditioning and e-mobility. It features two Fischer Core hybrid connectors with 8 electrical contacts and 1 fluidic tube resisting high mating cycles.



Power and fiber optic

For data transmission in the high-performance scanning systems used for the automatic optical inspection of brake shoes on Danish State Railways, ITTH GmbH & Co. KG relies on hybrid connectors from the Fischer FiberOptic Series.


The scanning systems at the Odense and Kolding stations that were installed in the track bed capture images of the brake shoes as the trains pass over them thanks to high-performance camera systems transmitting information at a speed of 10 Gbit/s. Since the system is located in the track bed, the connectors must withstand environmental conditions like snow, rain, dust and be resistant to damage from oil and gasoline.
