Fraba Absolute Rotary Encoders
Motion control applications – ranging from factory automation to control systems for construction equipment – require precise, real-time information about the physical position of mechanical equipment. Absolute rotary encoders can provide precise and unambiguous measurements of the angular positions of joints, drive shafts, pulleys, etc. in real time. This makes absolute rotary encoders an ideal way of linking mechanical components to an electronic control system.
Absolute Rotary Encoder Measurement
Absolute rotary encoders are capable of providing unique position values from the moment they are switched on as well as immediately after a power loss. This is accomplished by scanning the position of a coded material. All positions in these systems correspond to a fixed code. Even movements that occur while the system is without power are translated into accurate position values at once when the encoder is powered up again.

Single turn absolute encoders are systems that measure absolute positions for one turn of the shaft (up to 360°). After one turn the measuring range is exceeded and loops back to the starting value. However, in many applications several turns of the shaft must be distinguished. In these cases, multi-turn absolute rotary encoders will keep track of the angle position of the shaft while also providing code information about the number of turns turned as well.
