Today, precise measured values are required for real-time control. Rotary encoders with their own bearings and a wide variety of housing designs are used in this instance. A typical feature of these measuring systems is that the scanning unit and the target wheel are integrated in a single housing. Both components are precisely matched to each other. With pulse rates of up to 10,000 increments per revolution, the encoders cover all measurement requirements in the vehicle and have proven themselves in railroad rolling stock for decades.

Proven incremental rotary encoders

Our proven magnetic incremental encoders acquire the change in angle on a rotating shaft. The integrated sensors scan the built-in target wheel in contactless mode. The magnetic sensor system supplies 1-V_pp differential signals, HTL or TTL signals. The direction of rotation, the distance traveled and the speed of the rotating shaft can be determined from the signals generated, as an axle or motor encoder.

One axle encoder – many output signals

We offer special multi-channel axle encoders for wheel slide protection, train protection and secondary applications on the bogie. They provide different signals for several controllers and thus utilize their full potential. The sensors emit independent square-wave signals on up to eight channels. The push-pull electronics generate up to three different pulse numbers. Output is either in voltage or current levels. The channels can be configured and output either individually or in groups with fixed phase relationship. This allows the characteristics of the output signals to be matched accurately to the control units. This solution is individually tailored to the application.

Measuring systems for high loads

Extreme shaft loads frequently occur in rail transport. We offer precision encoders with a special coupling for this special load. The integrated and flexible hollow shaft coupling with a diameter of 20 mm enables attachment to motors with high axial and radial shaft movements. Alternatively, a rotary encoder series with a 16 mm solid shaft is available. Up to 5 independent and fully encapsulated sensor modules can be placed in a stainless steel housing. We adapt each module individually to your application and the control system. The system thus offers a wide range of applications.

Withstanding extreme weather conditions

All rotary encoders provide accurate measured values even under changing temperatures, humidity, strong vibrations and condensation. Additional protective measures can be selected for special environmental influences, such as protective coatings or condensed water outlets. Talk to us.
