CNT-723 Pulse counter with high-speed analog output

The CNT-723, an efficient pulse counter, outputs analog voltage proportional to the angle of a rotary encoder or the position of a linear scale at high speeds.
It has been designed for the measurement of rotation angle of power trains. For example in case of motor and controller testing, tire testing, engine testing or for similar applications.
