Is your control cabinet wiring becoming increasingly confusing?

Is the amount of wiring in your system constantly growing?


Our new CONEC IO distribution boxes offer you maximum flexibility and adapt seamlessly to a wide range of applications – from simple signal distribution to intelligent communication with modern control systems.

Depending on your requirements, passive solutions for fast and uncomplicated signal distribution or active IO boxes with integrated electronics are available. These enable direct and efficient connections to controllers via common fieldbus systems or Industrial Ethernet.

Active junction boxes PROFINET


Our distribution boxes with PROFINET network protocol enable easy integration of standard input and output sensors via binary signals – the ideal basis for modern automation solutions.

For more complex applications, powerful master boxes with IO-Link interface are available. They ensure the seamless integration of high-quality IO-Link sensors, creating greater transparency, extended diagnostic options, and higher efficiency directly in the
field.

  • As independent or master
  • No. of ports: 4 x M12 or 8 x M12

Active junction boxes EtherCAT


Our active distribution boxes with EtherCAT network protocol offer maximum speed, precision, and flexibility—ideal for demanding automation tasks.

Direct connection to the EtherCAT system allows inputs and outputs to be recorded and controlled decentrally – in real time and with minimal cycle times. This means you benefit from particularly reliable data transmission, optimal synchronization of your processes, and a future-proof solution for modern industrial applications.

  • As independent or master
  • No. of ports: 4 x M12 or 8 x M12

Active junction boxes IO-Link


Our active distribution boxes with IO-Link serve as compact slave boxes that can be connected directly and easily to an IO-Link master. They enable simple and reliable connection of sensors and actuators – without the need for complex individual cabling.

Thanks to digital IO-Link communication, valuable diagnostic, status, and configuration data is transmitted bidirectionally in addition to switching signals. This creates transparency, facilitates maintenance, and increases the availability of your system.

  • No. of ports: 8 x M8 or 8 x M12
  • Size supply ports: M12

Passive junction boxes


Our passive distribution boxes are the ideal solution for signal and voltage distribution in industrial applications and ensure service-friendly, space-saving, and clear cabling. This creates the basis for reliable and efficient automation. Thanks to their robust design, high protection classes (e.g., IP67), and clear labeling, the boxes can be installed quickly, ensure secure signal routing, and impress with their durability—even in harsh industrial environments.

With compact designs, optional M8 or M12 connections, and a variable number of ports, they offer flexible application options and can be optimally integrated into different automation concepts.

  • No. of ports: 4 x M8, 4 x M12, 8 x M8 or 8 x M12
  • Size supply ports: M12, M16 or M23

Enclosure technology


Distribution boxes have been a necessary hardware component in mechanical and plant engineering for decades. They serve as extended input and output interfaces of the electrical control.

CONEC designs and produces customer-specific distribution box housings with directly molded M8/M12/7/8“ or hybrid interfaces; other industrial interfaces are also possible on request. The builtin electronics in the form of the circuit board are installed by the customer. In terms of color, design and logo, the boxes are manufactured individually according to customer specifications.

CONEC IO systems – junction boxes

APPLICATION EXAMPLES:


Active distribution boxes:

Automotive production with IO-Link sensors: Active boxes capture signals from IO-Link sensors at robot stations, transmit status and diagnostic information to the PLC in real time, and thus enable efficient operation.

AdobeStock_275809291_Drehmaschine_LP_IO-systemeWEb80

Machine control via EtherCAT: Active boxes are used in CNC machines or packaging systems to capture inputs and outputs decentrally and transmit them directly via EtherCAT with minimal cycle times and wiring effort.

Process automation in the chemical or pharmaceutical industry: Active boxes connect field sensors such as light barriers or level sensors directly to the controller. Digital communication allows process data to be monitored and automatically logged.

Passive distribution boxes:

Cabling of conveyor systems in logistics: Passive boxes bundle signals from proximity sensors or limit switches along a conveyor belt. This makes the cabling clear and easy to maintain.

Passive boxes are used in production machines to clearly distribute binary signals from level sensors, safety switches, or valves. This saves installation time and reduces cabling errors.

CONEC provides the right connectivity for your active and passive distribution boxes – from versatile distribution systems to custom-assembled connecting cables – reliable, robust, and precisely tailored.

System solutions accessories- Junction systems


Distribution systems with IP67 protection allow particularly economical and efficient wiring of sensors and actuators at field level. They are used wherever spatially distributed signals need to be clearly bundled and quickly connected to higher-level controllers.

Depending on the application, the signals are forwarded directly to the control system via connected cables or connector interfaces – for a clear structure, simple installation, and high operational reliability.
