westermo威斯特摩设计和制造用于严苛环境中关键系统的数据通信产品。这些产品不但被用于交通、水利和能源等社会基础设施行业，而且还被用于采矿和石油化工等行业。

人们逐渐认识到工业数据通信的要求和一般商业数据通讯是不同的：工业数据通信的运行条件恶劣，预算使用寿命长达10年以上，并且一旦发生故障会造成严重的后果。因此，导致了对工业级数据通信需求的快速增长。

westermo威斯特摩正在快速成长，目前拥有200名员工，2016年全球销售额超过3.3亿人民币。研发和生产全部在瑞典Stora Sundby和Västerås工厂进行。

在欧洲、美国、新加坡和中国都设有销售和技术支持中心。westermo威斯特摩还在全球的其他重要市场中拥有众多合作伙伴。

悠久的工业数据通信传承
 
westermo威斯特摩成立于1975年，工业数据通信网络的初期。公司创始人Tore Andersson认识到工业环境数据通信可靠性的需求正处于起飞阶段。当时的数据通信标准是RS-232，只能够完成数米的数据传输，并且容易受到工业环境中的噪音和接地回路影响。为此westermo威斯特摩提供了KM-1的解决方案，这是一款简洁的隔离线路驱动器，能够实现长达18km的数据通信。
 
 
在此后的20年里，20 mA电流环路、RS-422和RS485工业数据通信标准先后问世，westermo威斯特摩也一直持续提供最可靠的隔离和防护解决方案。预见到DIN导轨在工业机柜应用中为客户带来的效益，westermo威斯特摩推出了首款集成安装夹的工业数据通信产品。它是专为在机箱中安全便捷地安装设备而设计，该安装夹至今仍在使用。
 
1996年，针对于工业用户能够可靠连接偏远无人值守的工业设备，westermo威斯特摩推出了TD-22。
 
作为首款真正意义上的工业电话调制解调器，TD-22外壳采用westermo威斯特摩 DIN导轨设计，专为确保在最恶劣环境中设备的持续运行而设计。 TD-22将westermo威斯特摩的业务带入到一个新的阶段。
 
随着业内不断采用新的数据通信标准，westermo威斯特摩在市场上首个推出了支持工业以太网通信标准的产品。在2000年，westermo威斯特摩发布了ED-10，它能够通过以太网连接旧串行协议。随着工业以太网的发展趋势继续加快，westermo威斯特摩开始着手开发以太网交换机，并于2004年首次推出SD-300。
 
2005年，westermo威斯特摩收购了稳固网络专家OnTime Networks AS公司，通过这次收购，获得的技术（如FRNT）使得我们能够提供业内最快的自愈环网。从而推动了管理型以太网交换机业务的发展。
 
发现使用SHDSL技术能够重新利用旧电缆实现长距离以太网连接的潜力后，westermo威斯特摩在2006年推出了一个重大创新ddw-100It。Wolverine DDW-100是一款革命性的产品，能够为客户显著节省时间和节约成本。同时，westermo威斯特摩使用的创建弹性安全网络的技术，继续引领市场。
 
2008年1月1日，westermo威斯特摩公司被北尔电子集团收购。北尔电子集团承诺持续注入资金，使得westermo威斯特摩能够继续开发面向工业以太网市场的创新产品。
 
随着以太网络的日益复杂化，以及客户使用的IP协议数量越来越多，westermo威斯特摩意识到对于交换机的管理，拥有自己的跨平台软件方案变得日益重要。在2009年，westermo威斯特摩推出了支持WeOS操作系统的Redfox工业路由交换机。从此，这种稳定易用的解决方案成为了westermo威斯特摩产品的核心。
 
westermo威斯特摩不断探索新兴市场， westermo威斯特摩通过与业界的密切合作，针对不断发展的列车车载以太网络市场，推出的westermo威斯特摩IP列车解决方案包括了一系列坚固型的交换机。2012 年推出了Viper系列。
 
westermo威斯特摩现在拥有强大的研发团队，并继续致力于开发一流的工业网络。

Westermo designs and manufactures data communications products for mission-critical systems in physically demanding environments. The products are used both in social infrastructure, such as transport, water and energy supplies, as well as in process industries, such as mining and petrochemical.

The requirement for industrial grade data communications continues to grow as industry understands that its needs differ from that of the corporate IT world. In industrial environments operating environments are tough, expected lifetimes are in excess of 10 years and the impact of failure in the field can lead to business threating situations. These factors have resulted in a demanding and fast growing market place.

The company is growing rapidly and currently has over 200 employees and global sales in excess of €50m. All development and production takes place in Sweden at the company's facilities in Stora Sundby and Västerås.

Westermo has sales and support offices around Europe and in USA, Singapore, China and Australia. Westermo also have a number of partners based in other key markets around the world.

Westermo is a wholly owned subsidiary of the Beijer Group.

Westermo was established in 1975 during the infancy of industrial data communication networks. Tore Andersson the founder of the company recognised the need for reliable data communications in the industrial environment at an early stage. The prevalent data communication standard at the time was RS-232 which could manage to transmit data only a few metres and was susceptible to the noise and earth loops found in industry. The solution was the KM-1, a simple but elegant isolated line driver that would allow communications out to as far as 18km.

Over the next 20 years industrial data communications standards like 20 mA current Loop, RS-422 and RS-485 appeared and Westermo was always able to offer the most reliable isolated and protected solutions on the market. With much of this equipment finding itself in industrial cabinets Westermo were early to see the benefit of the DIN rail mount for its customers and introduced the first industrial data communications products to the market with an integral mounting clip. This clip, still used today, is actually designed into the case making the mounting of the device both secure and easy.

By 1996 Westermo were again innovating in the market place when they recognised the huge benefits that industrial users would gain if they could reliably connect to industrial equipment in remote unmanned locations. The TD-22 was the first truly industrial telephone modem. Built into the Westermo DIN rail box and designed to ensure continuous operation even in the worst environments the TD-22 helped to drive the Westermo business to new levels.

Westermo industrial modems and converters

As industry continued to adopt new data communications standards Westermo was again one of the first to market with products that supported the Ethernet standard for industrial applications. In 2000 Westermo launched the ED-10 to allow old serial protocols to be transmitted over Ethernet. As the Industrial Ethernet trend continued to gather pace Westermo started to develop its own Ethernet switches for the first time, releasing the SD-300 in 2003.

In 2005 Westermo acquired, robust networking experts,  OnTime Networks AS to give a boost to the managed Ethernet switch business. With this acquisition came technology like FRNT, allowing Westermo to offer the fastest healing ring networks available to industry.

It was in 2006 that the next major innovation occurred when Westermo saw the potential in using SHDSL technology to allow industrial users to make Ethernet connections over long distance by reusing old cables. The Wolverine DDW-100 was born, a revolutionary product capable of delivering huge savings in both time and cost for the customer.  Westermo continue to lead the way in this market having adapted the technology further to allow the creation of resilient and secure networks.

1st January 2008 saw Westermo acquired by the Beijer Group of companies who have continued to channel increased investments towards Westermo allowing the company to continue to develop further innovative products for the growing industrial Ethernet market.

With Ethernet networks getting ever more complex and increasing numbers of IP protocols being used by industrial customers Westermo recognised the benefit of having its own cross platform software solution for switches.In 2009 the Redfox Industrial Routing switch was launched including the WeOS operating system. This incredibly robust and easy to use solution has been at the heart of every Westermo product since that date.

Westermo’s ability to design industrial Ethernet switches to operate in the worst environments led the company to explore interesting new markets. One in particular was the evolving market for Ethernet networks on trains. Working closely with the industry resulted in the Westermo IP train solution including a range of the most robust switches ever designed, the Viper family, being released in 2012.

Westermo now has its largest R&D team ever and continues to be a company working to develop the best industrial networks.
