Key specifications
Connector type: M12 straight
Pin count: 4-pin
Application: PROFINET and Ethernet
Shielding: Integrated for signal protection
Design: Industrial grade for field assembly
How to use
To install the connector, strip the outer jacket of the compatible industrial cable to expose the individual conductors. Insert the wires into the internal terminal block according to the required wiring standard for your specific Ethernet or PROFINET application. Once the connections are secured, assemble the housing components by tightening the threaded parts to ensure a proper seal and strain relief. Finally, screw the connector onto the corresponding M12 port on your device until it is firmly seated.
What to consider before purchase
Verify the pin configuration matches your existing hardware
Ensure the cable diameter is compatible with the connector's strain relief
Confirm the environmental requirements of your installation site
Usage recommendations
Always ensure that the cable shielding is correctly terminated to the connector housing to maintain the intended electromagnetic protection. Regularly inspect the connection points for signs of wear or vibration-induced loosening in high-movement applications.
