LongLife technology-based HeavyDuty tachogenerators utilize a silver track integrated within the commutator. These tachogenerators offer optimal signal quality, catering to high control dynamics, exceptional durability, and unparalleled extended operational lifespan. Furthermore, the LongLife technology excels in accurately detecting low speeds in real-time applications. These are often referred to as "tachos", used to produce an output voltage that corresponds to the speed. These devices operate through a generator to generate the output voltage, eliminating the need for additional electrical power. As a result, they offer a combination of strong signal dynamics and durability.
