The proven

Tacho generators are analog transducers for instrumentation and control technology. The permanently excited generators form the speed with which they are driven to a voltage proportional to that speed. Thanks to their robust design and construction they are suitable for larger industrial drives. Depending on the requirements the tacho generators are produced in customized sizes and connections as well as in a variety of voltage versions. They are available with IP rating IP55 to IP68.
