Hybrid connectors

Today’s devices are more complex, and they often require connections of fluid (liquid or gas such as helium, compressed air, etc.), optical fiber and electronics.


Each of these connections must be made correctly, every time, without any room for error or misconnection.


With the variety of functionalities and options available, end users can find it confusing and overwhelming to figure out what to connect where. Wrong connections can lead to safety issues, time delays, and damaged equipment.


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.


* N.B. In the connector industry, the term hybrid is also used for mixed connectors combining several power and signal contacts within a single body, e.g., the highly engineered, ultra-dense Fischer MiniMax™ connector with 6 power and 24 signal contacts in Ø 14 mm (‘size 10’ per Fischer Connectors reference).

Examples of high-performance hybrid connector applications


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.
