Mar 7, 2022 · Among all the coding types of M12 connector , A B D X coding is the most popular and has been used for a long time . X coding connectors are more and more popular in high-speed industrial Ethernet , and there is a trend to eventually replace A D coding in industrial Ethernet applications .

M12 D-code : 4 pin , widely used for 100M data transmission , such as industrial ethernet , machine vision. M12 X-code : 8 pin , widely used for 10G bps data transmission , such as industrial ethernet , machine vision.

Unlike traditional RJ45 connectors found in data centers, these connectors stand up to rugged industrial environments since they tightly thread to devices with M12 connections, sealing out contaminants and resisting shaking loose from vibration.

In addition, shielding is available in most coded M12 connectors. For example, X-coded connectors are specifically shielded by the design of their coding. The most common types of coding include: A-coded for sensors, dc power and 1 Gbit Ethernet; B-coded for Profibus; C-coded for ac power; D-coded for 100 Mbit Ethernet; X-coded for 10 Gbit Ethernet

D-code M12 connectors are almost exclusively used for industrial Ethernet applications but may also be used for fieldbus applications such as Profinet/Interbus, EtherCat, PoE (Power over Ethernet) or Ethernet/IP use cases.

Unlike general plug-and-play connectors, M12 connectors come in various coding types, represented by letters like A, B, C, D, X, etc. Each coding scheme has a distinct pinout configuration that determines the function of each pin in the connector.

M12 Connector pin configurations: 3 pin, 4 pin, 5 pin, 6 pin, 8 pin,12 pin, 17 pin/plugs designed for demanding industrial/ethernet applications. Available in brass-nickel or stainless steel, search our IP67/68 M12 connectors in stock worldwide.

Mouser offers inventory, pricing, & datasheets for D Coded M12 Circular Metric Connectors.

This series is a 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.
