Amphenol LTW’s Industrial Ethernet M12 to RJ45 Adaptor

June 5, 2012

For Ethernet networks that have to comply with protection class IP67/IP68, M12 plug connectors represent an attractive alternative to RJ45 - and are frequently more suitable. The M12 4Pin plug connector with D-coding has already been defined as an Industrial Ethernet standard according to IEC 61076–2–101. M12 connection technology is well established in sensor–actuator and fieldbus cabling and provides several advantages in industrial environments.

Amphenol LTW introduces M12 to RJ45 ODVA Compliant adaptors which provide a bulkhead style M12 connector on one and a shielded RJ45 jack on the other end to address specific Industrial Ethernet applications. This connector is “D-Coded” according to IEC 61076-2-101 and supports both 10Base - T and 100Base - Tx Ethernet connections in IP67/IP68 between devices on the machine and in the switching cabinet. Its unique and stylish designs are suited for device interconnection, can be mounted to panel boards, easy to install/uninstall and can be connected to non-waterproof conventional pre-terminated RJ45 plug.
