Company History

Günther Weber started his first business in Weinheim, Germany a small town near Heidelberg, with the development and production of sophisticated, electronic measuring equipment for the steel industry.
By working with this industry he learned how to design equipment and sensors capable to survive this harsh industrial environment.

1955
The first static infrared Hot Metal Detectors without moving parts and without adjustment potentiometers were introduced to the steel industry.
This development became the famous foto-captor that is still the leading HMD in the steel industry.

1961
The first two-wire inductive proximity switch was introduced by weber as a direct replacement for mechanical limit switches. This was the start of a new era in the sensor industry.
Many of today's well-known proximity switches can be traced back to the proxi-captor of weber.
Based on the early pioneering and developments by weber, Germany is today the leading world supplier of proximity switches.

1965
The small "Technology workshop" had to expand. weber founded weber Elektronik GmbH & Co KG at its new location in Kollmar, north of Hamburg, Germany.

1968
Two new families of products were emerging, both based on the calorimetric principle, utilized for the first time in industrial applications by weber:
the flow-captor and the vent-captor.
These products opened new markets for the company and they became the building blocks for growth in the coming years.

1979
The success of the captor line required a wider, international orientation for Sales, Marketing and Customer Service. For this weber Sensors GmbH was established.
The captor line was expanding. The requirement of reliable system in automation created new applications and with it came the development of new products.

1982
The increasing demand of captor products then required a factory for manufacture of standard products. Ireland was selected as the location and weber Sensors Ireland Ltd was established.
At the same time the sales in the UK started growing; weber Sensors Ltd. was then established in Southport, UK.

1986
There were already activities in the USA, and this was the right time to put more emphasis on the US market, weber Sensors Inc. was then established in North Lima, Ohio.

1997
weber Sensors Inc. (WSI) was then exclusively serving the steel industry. But soon the activities were expanded to the much bigger potential outside the steel industry. This required a better-suited location and WSI moved to Woodstock, Georgia.
Due to the evolving global economy in the 1990's the different weber companies started working together as a group, we call it the "captor group".

1999
The captor group was growing. For better coordination and support of the members of the captor group, captor Management Inc. was established.

2001
We have worldwide nearly 100 dedicated employees specializing in development, production, sales and customer support of captor products.

2006
weber sensors Inc move to new larger premises; Acworth GA, European companies restructured, Sales & Marketing, R&D and production split into independent companies; enabling weber to respond efficiently to customer demands and the changing global economy.
They all help our customers and partners with the task of advancing automation. OEMs throughout the world like to work with captor products from weber. Not only because of the wide application of captor products, but because of the global network of the captor group for customer service and support.

2016
The production in Ireland will be closed. Therefore the production capacities in Germany extend and additional jobs can be created.

In December weber Sensors Ltd. in Germany has transferred its business to the weber Sensors GmbH.
