Product Description
They are available as two-pair twisted-pair connectors M12 with D-coding and four-pair twisted-pair connectors M12 with X-coding.
The four-pole Ethernet M12 plugs and jacks with D-Coding supports 100 MBit/s. For higher data transmission rates up to 10 Gigabit/s, METZ CONNECT offers eight-pole Ethernet M12 plugs and Jacks with X-Coding.
In addition to their high mechanical and electrical resistance, these rugged Ethernet M12 plugs and jacks are resistant against dirt and humidity once they are plugged in, as they fully meet IP67 standards to ensure safe contacts and trouble-free data transmission.
With a range of fully shielded solutions and IP67 protection in mated form, end users can choose individual product components for specific requirements up to a complete network solution, from PCB/device level all the way back to the control cabinet.
