Pioneer in Fiber Optic Networking from Hamm, Germany

MICROSENS GmbH & Co. KG was founded in 1993 in Hamm, North Rhine-Westphalia, and is today one of the world's leading manufacturers of fiber optic transmission systems. The company consistently develops and manufactures its products in Germany – for maximum quality and short supply chains.

The product portfolio includes industrial Ethernet switches, media converters, SFP transceivers, patching solutions and smart building components. The focus is on reliable communication under the harshest conditions: harsh industrial environments, extended temperature ranges from –40 °C to +75 °C, and fault-tolerant ring topologies are MICROSENS core competencies.

In addition to classic network components, MICROSENS offers future-proof infrastructure for building automation digitisation with its Smart Building Solutions division – a growing market segment for facility management, healthcare and public institutions.

► Frequently Asked Questions about MICROSENS Products
What ambient temperatures are MICROSENS switches suitable for?
Industrial Ethernet switches from the Entry Line and Profi Line are designed for operating temperatures of –40 °C to +75 °C, making them suitable for outdoor installations, unheated halls and control cabinets in industrial environments.
What is the difference between Entry Line and Profi Line?
Entry Line switches are cost-effective plug-and-play solutions for simple industrial networks. Profi Line switches offer advanced management functions and the patented ring protection for highly available, mission-critical networks.
What does FTTO mean and who is it suitable for?
FTTO (Fiber to the Office) means fibre optic cabling running directly to the workstation. MICROSENS offers compact Micro Switches for this purpose, installed decentrally in the ceiling or floor. This concept is particularly suited for new-build projects in offices, hospitals and educational facilities.
