Molex Joins Single Pair Ethernet Industrial Partner Network

July 1, 2020
To help advance its Industry 4.0 technologies, Molex joins other technology suppliers in supporting the adoption of an Ethernet technology that reduces wiring requirements and enables miniaturization.

The Single Pair Ethernet (SPE) Industrial Partner Network is a collection of companies that promote and support the adoption of SPE technology to foster the growth of Industrial Internet of Things (IIoT) and Industry 4.0 applications. SPE describes the transmission of Ethernet over one pair of copper wires. In addition to data transmission via Ethernet, SPE also enables a simultaneous power supply of terminal devices via Power over Data Line. Previously, this required two pairs for Fast Ethernet (100MB) and four pairs for Gigabit Ethernet. 

According to Molex, being a member of the SPE Industrial Partner Network enables the company to fortify its Industrial Automation Solution 4.0, an end-to-end system that includes devices such as controllers, gateways, and I/O modules, as well as platforms to develop cloud-based applications. 

“IIoT and Industry 4.0 are driving new standards in wired connectivity for smart factories, which require fast and reliable data transmission from devices to the cloud. At the same time, demand is on the rise for compact, space-saving, and lighter-weight industrial infrastructure,” said Johann Ried, global product manager, Molex.

SPE technology addresses these trends because its one twisted pair of copper wires can transmit data up to 1,000 meters at high speeds. Also, the technology’s use of less wiring enables miniaturization and design flexibility. 

Based on industry standard IEC 63171-6, SPE conforms to IEEE 802.3 for uniform Ethernet transmission standards. Molex says this makes it possible to use Ethernet to integrate process data from industrial devices into existing Ethernet infrastructures.
