For many years, LTN Servotechnik has been developing and manufacturing customised rotary encoder solutions for extreme environments to enable precise measurement of movements and positions. Rotary encoders (or angular position encoders) are optical, magnetic or mechanical sensors which form signals from movements. They detect the current position of a shaft and convert even fractions of an angle degree to an electrical signal.
The digital output signals of a rotary encoder are the starting point for modern, high-precision position control systems. Thus, a drive unit can perform reproducible movements and return to the home or reference position after a work process.
