Optical incremental encoder simplifies assembly
Leine and Linde's new 2000 series of bearing-less optical encoders is targeted at plant and machinery automation applications where precision speed feedback control is required for large diameter drive shafts.
Available in the UK from Mclennan Servo Supplies, the encoders can be used on shaft diameters up to 1m. With a radial air gap requirement of up to 2.6mm between the ring and the separate measuring head, they can accommodate large shaft run-out as well as high levels of shock and vibration.
Furthermore, the construction of the ring, which is supplied in sections that are precision clamped around the shaft, is said to facilitate straightforward assembly on the machine.
The separate encoder ring segments can be fixed by face mounting to a flange with axial screws or with a special ClampFit solution that automatically tightens the complete ring encoder around the mating shaft without the need for a flange.
The speed pickup/measurement unit is available with several standard interfaces for incremental signal output.
