Modular unit concept

The GSt-A family of devices is being expanded to include modular operating variants in the display sizes 4.3", 7", 10" and 12.3". Equipped with state-of-the-art processor technology, the use of Birdeye functionality and AI-controlled workspace monitoring of the mobile working machine is realized. The development of a tactile display keyboard sets new standards in terms of flexibility, application diversity and user-friendliness in machine operation.


Company anniversary

On 11th of May 2022 the company Graf-Syteco celebrates its 40th anniversary. After the Bauma trade fair in Munich was postponed twice due to the pandemic, the company will finally present itself again with fresh ideas and new products at the world's largest construction machinery trade fair from October 24-30, 2022.


Growth in crisis

Despite the major challenges in the global procurement market caused by the Covid 19 pandemic, Graf-Syteco generated further growth in 2021. The establishment of an external engineering office in Heilbronn strengthens the company's consulting and development services area. Shortly after the series launch of the 3 new HMI from the GSt-A family with 4.3", 7" and 12.3" displays, Graf-Syteco has already convinced several major customers to use these powerful devices. A new company cooperation opens the entry into the US market.



With the market launch of the new, state-of-the-art HMI series "GSt", which began in 2020, Graf-Syteco is ideally positioned to meet the latest requirements in the areas of user experience, technical functionality, design language and robustness for use on mobile machines. The virtually reflection-free displays can be easily read from any direction, even in the strongest sunlight. All devices are available with robust die-cast aluminum housings and are suitable for both indoor and outdoor installation/installation.


Innovation and steady growth

In 2019, the company has grown to over 70 employees and is successfully expanding its product portfolio to include engineering services, technology consulting, and expert workshops and training. With an increased focus on the area of research and development, functional safety and customer-specific system integration, Graf-Syteco continues to focus on innovation, the future and steady growth.

Bauma Trade Fair 2019, Munich
The Graf-Syteco team proudly presented the new device series GSt-E in 10.1-inch display format. The visitors could admire all devices in action by means of a mobile crane. The devices impress with a solid aluminum die-cast housing, a sophisticated cable concept, a safety function by emergency stop as well as excellent readable displays, even in sunlight.

2015 - 2018

New building and change of management

Since the move to the new and modern low-energy company building with continuous solar facade, Jürgen E. Müller has strengthened the Graf-Syteco team as the new managing director in 2015.

In June 2016, Graf-Syteco completed the certification of its quality management system according to ISO 9001:2015. Since then, the company has been put to the test every year and has been able to successfully re-certify on an ongoing basis due to its high, internal standards and continuous improvement processes.

In 2016/2017, new body-mounted operator panels in 7-inch format are developed, which quickly found their place in construction machinery and municipal utility vehicles and are now produced in large quantities.

With the retirement of Martin Graf, Jürgen E. Müller becomes a shareholder of Graf-Syteco in 2018, together with the two sons of the company founder, Fabian and David Graf.

Also in 2018, the software concept "GSe" is presented as well as the trademark registration of the associated components VISU, CTRL, OS and CON.

From 2011


Since 2011, Graf-Syteco has been offering high-resolution displays (3.5 to 7 inches, with and without touch operation) with the D-Series operating and control units, which are designed for installation in individual dashboards. These devices are perfectly complemented by additional K-Series keypads, which are freely programmable, display machine states and can even take over control functions.


AT and MCQ series

Equipped with fast processors, the AT device series is launched at the beginning of the year 2000. The development of proprietary software and the use of ARM processors subsequently lead to the MCQ device series with display sizes from 4.3" to 10.4". These devices combine for the first time the idea of display, operation and control in one product. They are very popular on the market, especially in the application area of mobile machines, and are used permanently by customers due to their robustness.


Successful at trade fairs

In the 1990s, Graf-Syteco regularly presents itself at the Hanover Fair as well as at the SPS Fair, which is held in Nuremberg for the first time in 1997, as a competent manufacturer of operating and control solutions for the construction machinery market. Through appearances at Agritechnica and Interschutz, the company is additionally able to inspire and win important customers in the agricultural technology and fire fighting sectors.

Since 1982

Swabian tinkering meets engineering know-how

Since its foundation in 1982 by the engineer and Swabian tinkerer Martin Graf, Graf-Syteco has developed from a 2-man craft business into an internationally active medium-sized technology company. In the 80s the success story starts with then new electronic meters, which are replaced in the following decade by text displays and devices with modern CAN bus technology.
