Westermo design and manufacture robust data communication devices for harsh environments. We supply products that provide the network communication infrastructure, derived from proven commercial technology, for control and monitoring systems that are used in mission critical solutions where commercial grade products are not sufficiently resilient.
A global player in train and trackside networks
Westermo was established in 1975. The head office is located 100 miles southwest of Stockholm in Sweden. Over the past three decades Westermo has grown with sales and support units being established in Sweden, UK, Germany, France, Singapore, North America and China as well as partners in many other countries of the world.
Over its long history Westermo has evolved from supplying RS232 line drivers and then to DIN rail mounted tele-modems. With the advent of Ethernet as the de facto standard for data communications in many industries, Westermo developed an extensive range of robust Ethernet switches and routers.
All Westermo products are designed to operate in the kind of harsh environments located on the trackside and many of these devices carry the “Network Rail Acceptance”. Westermo also has its own expert team for the specialist sector of train networks.
