Single-Pair Ethernet 4000 Series Connectors and Cables

Bulgin's single-pair Ethernet (SPE) delivers uninterrupted IP communication from servers and the cloud down to the device level

Image of Bulgin Single Pair Ethernet 4000 SeriesBulgin 4000 series SPE connectors join the circular data connector family. They are available with flex variations, front and rear panel mounts, and 1 m, 2 m, 3 m, and 5 m cable lengths in 22 AWG and 26 AWG options.

The 4000 series SPE range follows the 10BASE-T1L protocol, with uninterrupted IP communication from servers and the cloud down to the device level. They are environmentally protected up to IP68 when mated. The 4000 series connectors feature a robust mechanical design with a secure 30° quick-twist bayonet connection. Available options include flex patch cords with various terminations and panel-mount connectors.

SPE can supply power and data transfer in sophisticated industrial IoT implementations using Power over Dataline (PoDL). They are compact, robust connectors with a thinner cable diameter, making the 4000 SPE suitable for harsh environments.

SPE is a flexible technology that can be customized to suit many applications. Patch cord lengths, transmission speeds, and network topologies can be adjusted to fit most situations.
