DC Tacho DCT 22 0.52 Volt
Important information • Tacho with moving coil, maxon system. • Tacho with precious metal commutation. • To establish total inertia add motor and tacho inertias. • With the output shaft turning CW as seen from the mounting surface, the tacho output voltage will be positive at the + terminal. • A high impedance load is recommended at tacho terminals. • The tacho current should be kept low. • The indicated resonance frequency refers to the motor-tacho rotor system.
