PROmesh U3
Compact unmanaged industrial Ethernet switch with two RJ45 ports and one multimode fibre-optic port for reliable PROFINET and Industrial Ethernet connections.
Product Overview
The PROmesh U3 is a compact, unmanaged industrial Ethernet switch designed for reliable PROFINET and Industrial Ethernet connections in industrial automation environments. With two 100 Mbit/s RJ45 ports and one 100 Mbit/s multimode fibre-optic port, it provides a practical solution for connecting copper and fibre-based network segments.
The PROmesh U3 uses a robust metal housing and passive cooling, making it suitable for demanding industrial environments. Its compact design allows flexible installation on a 35 mm DIN rail, while integrated functions such as PROFINET prioritisation, VLAN and network protection features support reliable network communication.
The switch is designed as a plug-and-play solution and is particularly suitable for smaller and less complex industrial network structures where managed switch functionality is not required.
