Speed and position detection in heavy-duty applications
Fail-safe: Robust measuring system 
Flexible: The right solution for every installation situation 
Proven quality Mobile machinery, construction equipment, and special-purpose vehicles must be powerful, reliable, and ready for use at all times. In daily operation, they are exposed to wide temperature fluctuations, dirt, dust, and heavy vibration - and require components that deliver consistently precise performance under these demands.
Whether on construction sites, in municipal applications, in agriculture, or in special-purpose vehicles: our sensor solutions are designed for the most demanding operating conditions. They provide precise measured values for control, monitoring, and regulation tasks, supporting safe and efficient machine operation. The proven sensor technology accurately and reliably detects speeds, directions of rotation, and rotary and linear positions - giving you the foundation for greater operational safety and vehicle efficiency.
Our Condition Monitoring solutions further contribute to increased availability.
Bearing-free encoders such as the GEL 247 handle precise traction control in working machines such as dump trucks and tractors. Particularly in challenging terrain, reliable speed detection is essential to ensure traction, driving stability, and operational safety at all times.
For use under extreme environmental conditions, the robust sensor housing can optionally be further reinforced. Fully encapsulated electronics provide additional resistance to coolants, oils, and moisture. The bearing-free encoder withstands flying stones, heavy contamination, and other stresses encountered on construction sites, ensuring precise speed detection and long service life.
For optimal traction without slip or wheel spin when pulling away slowly under load on inclines, high-resolution speed signals are essential for precise drive control.
Our bearing-free encoder GEL SEI10 delivers custom signal patterns with pulse doubling. Thanks to its robust design, it is ideally suited for use in mobile working machines. Output signals are precisely matched to your existing controller, allowing seamless integration into your system.
We also offer the right solution for safety applications in autonomous working machines. Get in touch with us.
When traveling at low speeds, maneuvering, and working under high load, electric motors must run reliably, smoothly, and efficiently - even during frequent direction changes and at low speeds. Precise torque control requires rotor position sensors that detect rotor position contactlessly and with high accuracy.
This is where our VarioCODER comes in: it delivers stable, precise signals even under strong vibration and is ideally suited for use in electric motors in construction equipment, such as electric plate compactors.
For extremely demanding environments with dust, dirt, and high mechanical stress, we offer particularly robust, additionally protected rotor position encoders.
Reliably determining lift height and inclination - for example in concrete pumps, elevating platforms, and industrial trucks - requires absolute position values that are available immediately on power-up, without a reference run.
Our inductive absolute encoder GEL AIK10 detects positions and angles with high precision, ensuring maximum safety and efficiency in daily operation. Its contactless measuring principle makes it ideally suited for demanding industrial environments.
Monitoring axles, drive systems, and hydraulic systems provides valuable information for the early detection of bearing and gear damage as well as imbalances. Speed sensors, vibration sensors, and temperature sensors are used for this purpose. They help prevent unplanned downtime, increase drive availability, and support the efficient implementation of a predictive maintenance strategy.
Our Condition Monitoring solutions reliably monitor the condition of your mobile machinery and construction equipment — even under the harshest operating conditions. In addition to precise speed signals, the CombiCODER GEL 2475CM simultaneously captures vibration in three axes and temperature, combining the most important measured variables in a single robust, fully encapsulated housing.
Drive systems in large industrial vehicles face particular demands in terms of efficiency and service life. Especially when power take-off (PTO) systems are used to drive additional mechanical or hydraulic auxiliary units, stable and precise motor operation is critical.
The easy-to-integrate, high-resolution threaded sensor GEL 2460 enables low-vibration operation even under demanding conditions, such as extremely slow maneuvering under high load or simultaneous operation of work functions via the PTO system.
