The Mencom series has an M12 threaded connector, and we refer to this series with an MDE45 prefix.
The MDE45 is specifically used in Industrial Ethernet applications, and has teal cable using twisted pairs of wires inside. This connector has a unique keyway that is known as D-coded.
Murrelektronik has a wide product range and can offer connection accessories for all these areas.
