New IP20, M8, and Cable Assembly Options Extend Single Pair Ethernet from Control Cabinets to Field-Level and Edge Devices
ATTEND, a leading provider of advanced connectivity solutions, expands its T1 Industrial Single Pair Ethernet (SPE) portfolio with three new products that extend Ethernet connectivity across PCB interfaces, equipment connections, and industrial cabling. As industrial networks push Ethernet closer to sensors, controllers, and distributed edge devices, limited installation space and growing cabling complexity make network deployment more challenging. Single Pair Ethernet addresses these constraints by transmitting Ethernet data over a single pair of conductors, enabling smaller interfaces, reduced cabling, and simplified integration across distributed industrial networks.
New additions include an M8 SPE Two-Piece Insert, SPE IP20 Jack, and M8 SPE Female-to-Female Cable Assembly. Together, they add IEC 63171-2 and IEC 63171-5 interface options for complementary installation environments. IEC 63171-2 provides a compact IP20 interface for protected environments such as control cabinets, controllers, and enclosed equipment. IEC 63171-5 uses a rugged M8 form factor with higher ingress protection for sensors, actuators, and other field-level devices. By combining cabinet-side and field-side interfaces, the portfolio extends SPE connectivity from the control layer to distributed field equipment within a unified Ethernet architecture.
ATTEND's T1 Industrial SPE series supports IEEE 802.3 BASE-T1 technologies at data rates from 10 Mbps to 1 Gbps. Interface options are based on IEC 63171-2, IEC 63171-5, and IEC 63171-6. With Power over Data Line (PoDL), compatible devices can receive data and power over the same pair of conductors, reducing the need for separate power wiring. These capabilities support factory automation, industrial sensor networks, process control, and edge device applications.
“Industrial Ethernet is moving closer to sensors, actuators, and distributed edge devices, creating greater demand for compact interfaces and simplified cabling,” said Leon Hung, Product Manager at ATTEND Technology. “By expanding our T1 Industrial SPE series with IP20, M8, and cable assembly options, engineers can extend Ethernet connectivity from protected control environments to field-level equipment while maintaining a consistent network architecture.”
