Tips: What is the working principle of a smart photo tachometer?

A smart photo tachometer operates based on the photoelectric reflection principle. The small tachometer emits a light beam toward a rotating object, and when the light hits a reflective mark, the reflected signal is received by a photodiode and converted into an electrical pulse. Each pulse represents one rotation or a fixed position. An internal MCU counts the pulses within a specific time period to calculate the rotational speed (RPM). This non-contact method ensures fast, accurate, and safe measurement, especially for high-speed applications.
