Linear drives with displacement encoder

Drives with displacement encoder

Festo offers both rotary and linear drives with a displacement encoder. The displacement encoder is part of the controlled systems – it supplies the actual value with the current position. Potentiometers or contactless displacement encoders are used. The displacement encoders are integrated in many pneumatic drives. Alternatively, they can also be attached to the drive. The cylinder diameters vary from 18 to 100 mm, the stroke lengths from 100 to 2,000 mm.
