Single-pair Ethernet (SPE) is a powerful technology for realizing Industry 4.0 and IIoT applications. The Combicon range PCB (printed circuitboard) terminal blocks (photo) provide suitable connection technology. The networking of smart devices continues to advance. This applies in particular to sensors that are often exposed to higher-altitude ambient conditions when used in the field. In addition to the possibility of integrating an IP-protected connector into such field devices, there is also the option of using a cable gland to achieve the desired degree of protection. This means that the PCB terminal blocks, tested and suitable for SPE data transmission, can be used inside the devices. With clear color coding and intuitive handling, the blue and white wires of the SPE cable can be contacted clearly and safely. — Phoenix Contact GmbH & Co. KG, Blomberg, Germany
