Description

Electronic heavy-duty overspeed switch

The electronic overspeed switches monitor the factory-set speed with high switching accuracy, including low operating speeds. Alternatively, the overspeed switches can be used as standstill monitors. As a consequence, the overspeed switches play their part in system and personnel protection. The overspeed switches are installed on motors, for example in cranes, in mining operations as well as in rolling mills and more.
