Railroad Technology
Railroad technology places special demands on sensors and drives. In particular, the strong vibrations in rail transport require especially robust product solutions. The rotary encoders and generators developed specifically for railroad technology by Johannes Hübner Giessen are characterized by their reliability, durability, and customizability.
We offer innovative solutions for a wide variety of applications in railroad technology. Wear-free and durable magnetic rotary encoders enable high-precision traction control, even when climbing steep gradients.
TDP tachogenerators provide skid protection in a wide range of locomotives. Digital resolvers are used for reliable drive slip control. Synchronous generators are used, among other things, to supply power to diesel-powered on-board electrical systems.


We are your reliable partner for speedometers and sensor solutions in the railway sector. Our products, specially developed for 1:1 replacement, enable seamless integration into existing systems and have proven extremely successful in many projects. To minimize downtime and increase safety, we offer robust, wear-free, and durable sensors that provide you with reliable information on the system status.
