Smart Carbon Detection System


Combining safety and effectiveness, Schunk's smart carbon detection system for pantographs lets you know when it's time to replace the pantograph's carbon slide. Not only that, but the pantograph's smart carbon detection system allows you to focus on wear detection. When passing a fixed measuring point, the system detects whether the wear limit has been reached, giving you enough time to replace it.


The system can be configured in a few hours and savings begin immediately. This fixed detector is lightweight and easy to install on-site or in a parking lot. This also applies to RFID transponders on vehicles.
