M8 Profinet/Ethernet connectors are vibration-proof

Vibration- and torsion-proof connectors with D-coding and 360-degree shielding have been released by Provertha.

Now available in the of M8/M12 circular connector range, the M8 crimp CF connectors have 360 degree shielding with D code in protection class IP67.

The compact four-pin M8 connectors are specified by the PNO (Profibus User Organisation) according to the Profinet guidelines and enable robust and space-saving solutions for Profinet and Ethernet networks, says Provertha. The optimised design specifically meets the requirements for a functionally reliable Ethernet connection and interference-free data transmission in applications with high levels of vibration and torsion, such as in railway and transport technology. It can also be used in factory automation for automatic punching machines and robot applications.
