HARTING T1 Industrial Single-Pair Ethernet (SPE) Products

HARTING T1 Industrial Single-Pair Ethernet (SPE) Products feature a highly optimized, high-frequency design, shielding, and high mechanical robustness, making them an ideal choice to fulfill industrial SPE demands. The T1 products enable Ethernet data transmissions by using only two wires (TW1STER) and the simultaneous power supply for terminals via a Power over Data Line (PoDL). SPE offers barrier-free connections for equipment, sensors/actuator technology, and more by using end-to-end, IP-based communications up into the field level. This makes the field-level smart and simplifies the parameter setting, initialization, and programming. The set-up, operation, and maintenance of equipment become more efficient and more cost-effective. The complete wiring is simpler and also considerably faster to install.

HARTING T1 Industrial Single-Pair Ethernet Products offer end-to-end compatibility of devices, cables, and connectors at Ethernet speeds between 10Mbit/s and 1Gbit/s. The products provide a 60VDC voltage rating, 1000 mating cycles with IP20 protection rating, and an operating temperature range of -40°C to +85°C.

The T1 SPE products are well-suited for a variety of applications, including agricultural, automation, robotics, machinery, and transportation.
