Würth Elektronik Integrates Transformer and Current-compensated Choke in M12 Connector

July 20, 2021

Würth Elektronik has expanded its industrial Ethernet M12 connector prouct offering. The WE-LANMX M12 connector has a transformer and current-compensated choke are already integrated. With the manufacturer’s fitting screw connector, device developers and system builders can implement cabling that meets protection class IP67 used in harsh environments, if in mated and secured position. The connector is assembled on the board with through-hole reflow technology. This means that the data connection with WE-LANMX is protected against dust and water as well as rugged against vibrations.

WE-LANMX is easier and more space-saving than a conventional M12 connector, as the essential components are already integrated into its housing: The particularly small signal transformer WE-STST, the data line filter WE-CNSW featuring high common-mode attenuation, and the ‘Bob Smith’ termination for Ethernet. With the LCP housing material and special housing form, as well as the shape of the pins. Würth Elektronik has made the THT connector reflow solderable. The operating temperature of the WE-LANMX ranges from -40 to +85°C.

Commonly used in industrial applications e.g. factory automation, robotics, transportation technology, wind power plants and more, the connector is suitable for all types of 10/100Base-T Ethernet connections, such as EtherNet/IP, Profinet, EtherCAT or Ethernet Powerlink.

Würth Elektronik provides free samples for prototyping. WE-LANMX and the corresponding screw connection are available from stock without a minimum order quantity.

  • M12 connector with integrated transformer / common mode choke
  • Slim design
  • High mechanical stability
  • Through Hole Reflow (THR) soldering
  • Compliant with standard IEEE 802.3u
  • Operating temperature: -40 °C up to +85 °C
