RJ45 Industrial Connectors




Y-Con Industrial Connector System

Includes RJ45, ProfiNet and USB 




The Y-Con series connectors from Yamaichi Electronics Deutschland GmbH are designed for the harshest industrial applications, factory automation, Industrial Ethernet and other Fieldbus assemblies. It is a modular, flexible and extendable product line.

Yamaichi offers standard or customised cable assemblies with Industrial Ethernet digital cables up to CAT6A, and converter assemblies with M8/M12.  Cable assemblies are designed and developed by our in-house product management team and assembled in our factory in Germany according to the strictest quality standards, with functional and stress tests before delivery.


The Y-ConRJ45 industrial connector series can be used in Industrial Ethernet, Sercos automation bus and many other Fieldbus systems.


  • With or without EMI protection in full metal or plastic.
  • Protection to IP20, IP67, IP68, IP69K (EN60529 and DIN40050).
  • Operating temperature range of -40°C ~ + 120°C.
  • Warranted fully backward compatibility of the components.



Protection Standard

The approved Yamaichi Y-Con series is designed for toughest industrial applications.  With a modular, flexible and extendable product line that fulfills the stringent IP20, IP67, IP68, IP69K (EN60529 and DIN40050) environmental protection standards.

Power Supply and Data Transmission

The Y-Con RJ45 is the unique industrial-grade connector system which is based on RJ45-specification with additional integrated contacts for power supply. Although the Y-Con RJ45 series has an advanced design you will find they are compatible with other standard RJ45 applications. With plugs, jacks and patch-cables there is a wide range of high-quality products to fulfill your needs. The standard finish is a chrome plate body although a black chrome finish is available on request. With high-quality gold plated Solder, Crimp and PCB contacts ensuring secure data transmission and high currents are no problem. These products achieve a minimum of 5000 mating cycles.

Fast and Easy Field Assembly

The Y-Con product line consists of a large range of accessory options as well as fitting tools that allow easy field assembly.

High/Low Temperature and Shock Resistant

Most of the products in the Y-Con series operate within a temperature range of -40°C ~ + 120°C due to the use of high-quality materials. The IP6*- connector system was tested successfully against shock and vibration up to 50g (acc. DIN IEC 68-2-6). The IP20 locking mechanism of Y-Con withstands vibration-plagued applications and guarantees the highest plugging security.

Modular System Expansion

The modular concept of the Y-Con series can be expanded at any time as and when the application demands. Connection such as USB-A and USB-B can be adapted, exchanged or replaced in the same IP6* housing without expensive re-work costs. The Y-Con peripheral equipment for industrial environments follows the same idea, to design a flexible system expansion as effective as possible.
