10BASE-T1SA1 | USB to 10BASE-T1S Ethernet Converter

This high-speed USB 2.0 to 10 Mbps Ethernet converter is specifically designed for interconnecting USB interfaces with IEEE 802.3cg standard 10BASE-T1S Ethernet interfaces. As a network adapter, it seamlessly connects application devices to 10BASE-T1S networks via the USB 2.0 interface, addressing the protocol compatibility issue between general-purpose devices and industrial/vehicle networks. The converter integrates the LAN8670 single-pair Ethernet physical layer transceiver, supporting 10BASE-T1S standard single-pair twisted-pair transmission, and enables stable data interaction within a 25-meter range.

In terms of network topology and communication efficiency, the converter supports a Multidrop architecture, allowing multiple devices to share the same transmission link. Combined with Physical Layer Collision Avoidance (PLCA) technology, it effectively prevents signal collisions and enhances the communication reliability of bus-type networks. Its industrial-grade design is a core advantage — built-in ESD protection devices safeguard against electrostatic discharge (ESD) and surge interference, ensuring stable operation in harsh industrial environments with strong electromagnetic interference or vehicle-mounted scenarios, while protecting signal lines from transient voltage spikes.

Whether for interconnecting controllers and sensors using protocols like PROFINET and EtherCAT in industrial automation, data transmission in automotive electronic body control modules and low-speed sensor networks, or low-cost and efficient transmission needs in IoT and building automation, this converter reduces deployment costs through single-pair cabling and simplifies the debugging process via USB plug-and-play functionality. From technical adaptation to environmental protection, it provides a flexible and reliable connection solution for short-range, low-power distributed networks.
