miniCON – a mini CONnection with huge potential


This plug connector is the simplestsafest and most reliable way to connect your devices with power sources, data networks or each other. 

Thanks to foolproof, maintenance-free operation and a quick, easy installation, you will no longer need specialised staff in the future. Not to mention the significant cost savings you will benefit from.

miniCON is certified in accordance with ATEX and IECEx worldwide for Zones 1, 2, 21 and 22. What does that mean for you? Whether you work in the oil, gas, chemical, pharmaceutical, beverage or cosmetics industry, or even offshore or in shipbuilding, our miniCON is perfect for a wide range of applications wherever you need a reliable plug connector.



Due to their sophisticated design, the miniCON plug connectors are uniquely flexible, modular and convince through easy handling, cost savings and future-proof security. But what do we really mean by that? It's simple:



  • Complete freedom for any applications since all electrical connections between bus systems and a three-phase power supply (8-pole or 7-pole + PE, high-speed bus, 3-phase + auxiliary contact) are supported.
  • Autonomy, as the plug connectors can be coded by the customer and subsequently adjusted at any time. 
  • No risk of mix-ups thanks to the self-finding system with three coding options for plugs that simply cannot connect with anything they shouldn’t connect with.
  • Plug & play enables quick and easy disconnection of the plug and thereby enabling use at other locations.
  • The connection cross-section from 0.25 mm2 to 2.5 mm2 provides outstanding flexibility when selecting electrical cables.



  • The plug connectors consist of a number of identical components, which can be combined to create a wide variety of different versions.
  • Modular with freely combinable components.
  • You could use the cable glands which are already available to you without having to place any additional orders.



  • Easy and quick assembly due to the low variance in parts and logical design.
  • Incorrectly assigned pins are no longer a problem – with the snap-in function, it's easy to correct them.
  • The hot swap function enables assemblies to be replaced during ongoing operation by just one member of staff. 
  • Turn, contact and secure – establish mechanical and electrical connections in just three steps thanks to the simple turning mechanism.
  • The plug connector can be inserted and removed seamlessly with one hand, even while wearing gloves.
  • The built-in components of an Ex d enclosure can be aligned in 24 different ways using the positioning aid.



  • miniCON is maintenance-free. When your other devices require maintenance, you can perform this work quickly and easily – all you need to do is unplug the connector.
  • Fast maintenance means that you can significantly reduce the amount of downtime in your production facility.
  • At the same time, it guarantees quick commissioning, as there is no need of individual wiring on-site and the time needed for installation is much shorter.
  • Long approvals processes for hot work are now a thing of the past – thanks to hot swap technology, the plug connector can be safely disconnected mechanically and electronically at any time by just one person.
  • It also eliminates errors and troubleshooting in the plant, since all plug connectors are pre-mounted and tested by the OEM. 
  • One plug connector for all situations: Only the base part of the plug and coupling differs, while the rest remains the same, enabling you to reduce your storage costs significantly.



  • Would you like to trace all component parts? Would you like to create clear documentation through digitalization? No problem. miniCON is designed so that it can be integrated seamlessly. After all, serialization comes as standard with us.
  • It also supports modern maintenance strategies, which makes it even more future-proof. 



  • The pull brake is an extremely useful feature – thanks to acceleration during the separation, it enables a safe disconnection and a contact burn-off is avoided.
  • The locking mechanism with on/off display is another highlight as it enables you to determine at a glance whether your plug connector is connected or disconnected.

miniCON for Ex e and Ex d enclosures

Whether Ex e or Ex d - we have the solution. The 8-pole, explosion-protected miniCON plug connectors of the series 8595 can be effortlessly combined with Ex e or Ex d enclosures. Versions with prefabricated electrical lines are available for installation in enclosures. The plug connectors are available for device installation as device plugs and flange sockets.  The high-quality plastic or stainless steel plug connectors are extremely versatile in use and impress with their reliability. Thanks to the hot swap disconnecting capability, intrinsically safe signal and power supplies up to 500 V/16 A can be connected and disconnected reliably and safely without the need for a hot work permit. They are quick and easy to install thanks to their modular design and logically arranged components. Our patented one-hand operation also means that matching plug connectors, which can be defined by the installer using internal coding for up to three applications, can be connected in no time.


Inline applications

miniCON separates intrinsically safe signals and connection lines with increased safety in hazardous areas within Zones 1, 2, 21 and 22 quickly and safely, even under load. With a high transfer rate of 1 GBit/s, this plug connector system is ideally suited for all fieldbus installations.   You can use our plug connectors in measurement and control systems to connect actuators and sensors, or to connect motors, pumps and other electrical equipment with a current consumption of up to 16 A – all in next to no time. The electrical cables are crimped or soldered to establish a reliable connection.  With a compact design, wide variety of applications, easy operation and high safety levels, miniCON is the perfect solution for you.
