HARTING T1 Industrial M12 Single-Pair Ethernets

HARTING T1 Industrial M12 Single-Pair Ethernets deliver a highly optimized, high-frequency design, shielding, and high mechanical robustness. These T1 SPEs enable Ethernet data transmissions using only two wires (TW1STER) and the simultaneous power supply for terminals via a Power over Data Line (PoDL). The T1 Industrial M12 single-pair Ethernets feature -40°C up to 85°C temperature range, 500 mating cycles, AWG 28-22, up to 10Gbit/s transmission speed, and 60V voltage. These T1 M12 SPEs are shock and vibration resistance according to IEC 61373 category 1B (railway standards). Typical applications include industrial Ethernet cable assemblies, switches, IPCs, modems, HMIs, PLCs, sensors, and actuators.
