Eltra – Optical Multiturn Absolute Encoders

Rotary absolute encoders provide a unique digital code for each distinct angle of the shaft, storing the value of the actual position and, therefore, preventing the loss of information in case of restart of the system or power-loss. Thanks to the advantages featured by this type of sensors, Eltra's offer for absolute encoders in in constant growth, always in line with the latest innovations in technology.
