Würth Elektronik has introduced an industrial Ethernet M12 connector WE-LANMX with an integrated transformer and a current-compensated choke. The connector is assembled on the board with through-hole reflow technology, which means that the data connection with WE-LANMX is protected against dust and water as well as rugged against vibrations. It is suitable for all types of 10/100Base-T Ethernet connections, such as EtherNet/IP, Profinet, EtherCAT, or Ethernet Powerlink. Moreover, it can be used in industrial applications e.g. Factory automation, robotics, transportation technology, wind power plants.


WE-LANMX is a space-saving 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. The LCP housing material and special housing form, and the shape of the pins have made the THT connector reflow solderable. The operating temperature of the WE-LANMX ranges from -40 to +85°C.
