The BCX body control units provide intelligent power distribution and are available as a standard product as well as customer-tailored development. They can be used in various machine sizes and can, amongst other things, function as cabin control units.
The product spectrum of body control units can be subdivided into two development stages based on the know-how of the passive central electrics: 

BCX - I/O expansion (passive central electrics + I/Os)
Our body control units with I/O expansion are equipped as a standard measure with wakeup inputs and semiconductor outputs. All fuses and relays are equipped with a diagnostics function. The relays can also be switched via the control unit. This permits full integration into the vehicle network.

BCX - active / intelligent body control unit (passive body control system + I/O expansion + intelligence)
Our active and intelligent body control units combine a control unit and a central electric to form a single electric system.
Customer-specific developments can also be realized for intelligent central electrics.


We are proud of our products and solutions, but they really reveal their true colors when used by our customers. Whether digitalized, automated or electrified – mobile machines repeatedly delight with new innovations, in particular in terms of their user-friendliness, reliability and ability to integrate into work processes. Thanks to our customers, we are delighted to present a small selection here.


Our objective is to support our customers in all aspects concerning the digitalization, automation and electrification of their mobile machines. We consider the entire machine lifecycle and develop our STW product and service portfolio in alignment with this lifecycle. The ECO system, an open and holistic approach, facilitates the cross-topic integration of STW solutions. Furthermore, our product approach facilitates functional expansion through partner offers and hybrid, integrated products based on our system module.


The STW "ECO System" is characterized through the integration of systems and products which transcend the borders between solution areas. Our partners also supplement the STW product and services portfolio for the benefit of our customers. The open nature of the product portfolio permits easy integration of the products into third-party systems or the supplementation of our system through further products by third party providers.
