T1 Industrial Single-Pair Ethernet (SPE) Connector

HARTING’s T1 connector can accomplish communication across the common industrial Ethernet protocols (Ethernet/IP, Profinet, EtherCAT, and others) with a single twisted pair of wires instead of four or eight wires. This connector utilizes power-over-data-line (PoDL) technology to bring communication, voltage, and amperage needed to power the device.

With this connector, the number of connections on the device is reduced, eliminating the need for an external power supply, and the devices on the plant floor that traditionally communicate over Fieldbus protocols can join the same IP-based network as the other devices. This enables peer-to-peer communication, open-loop feedback of all devices, and smart functionality from the main control room to the device.

The T1 is the standard mating face for industrial single-pair Ethernet. The product ranges from IP20 to IP67 and is available in metric variants including M8 and M12. To be truly standard for industrial applications, the mating interface is designed to be the same and interoperable across all IP ratings.
