Механическая / промышленных / ход счетчика

Mechanical counters require no power since they are incremented by movement alone. Revolution counters increment one count per each 360° rotation of its shaft. Rotary or direct drive counters increment ten (10) counts per each 360° rotation of its shaft. Stroke or ratchet counters increment by a reciprocating 40° to 45° movement to the shaft. Typical applications include counting cycles of a machine, indicating physical positioning or measuring length
