Can single pair Ethernet (SPE) connectors replace RJ45 connectors in the trend of miniaturization?

SPE connector is an iterative product of RJ45, suitable for industrial Ethernet devices such as industrial switches, servers, controllers, sensors, etc. It is a new choice for Ethernet connectors that combines miniaturization and reliability, and can simultaneously transmit data and power.

The miniaturization advantage of SPE connectors is that they only require two contacts to achieve simultaneous transmission of signals and power, resulting in a volume of only 20% of standard RJ45 connectors. However, traditional RJ45 connectors, circular connectors, D-shaped connectors, and other solutions require larger installation space, making it difficult to achieve device miniaturization.

The mating reliability of SPE connectors benefits from a special snap on structure. The buckle can provide higher retention force for insertion than RJ45 connectors while ensuring convenient operation, effectively avoiding accidental collision and loosening of insertion.

The transmission performance of SPE connectors is also excellent. In terms of transmission distance, traditional RJ45 data transmission distance does not exceed 100 meters, while SPE connectors reach 1000 meters. In terms of transmission rate, SPE connectors can achieve a transmission rate of 1Gbps within a range of 40 meters. Provide a transmission rate of 10Mbps within a range of 1000 meters. In terms of power supply, traditional RJ45 connectors have a power supply of 300000 watts for POE and 500000 watts for SPE connectors under the IEEE 802.3at standard. Meet the stable transmission requirements of industrial equipment for data and power.

With the gradual promotion of Single Pair Ethernet (SPE) technology worldwide, it is believed that TXGA's SPE connectors will bring more breakthroughs to innovation in the industrial Ethernet field.
