Whether you are upgrading factory automation systems, integrating IIoT (Industrial Internet of Things) devices, or connecting remote monitoring equipment, our switches provide the robust network backbone your mission-critical applications require.

Engineered for resilience, our portfolio includes Fast Ethernet, Gigabit Ethernet, and PoE+ (Power over Ethernet) options to suit varying bandwidth and power needs. Built to withstand extreme conditions on the factory floor, these unmanaged switches feature wide operating temperature ranges (from -40°C to +80°C), dual redundant power inputs, and highly efficient low power consumption.

We understand that industrial physical space is often at a premium. Choose from compact, DIN-rail mountable enclosures for standard control cabinets, wall-mountable units for light industrial spaces, or bare-board embeddable switches designed specifically for OEM integration. For extended fiber optic reach, we also provide gigabit SFP media converters.

As a trusted UK manufacturer with decades of engineering expertise, Brainboxes stands behind the quality of our connectivity solutions. All our industrial network switches are backed by an industry-leading lifetime warranty and free, highly-qualified lifetime technical support.
