Precision Speed Control Solution

Available in the UK from Mclennan Servo Supplies, the encoder can be used on shaft diameters up to 1m, and with a radial air gap requirement of up to 2.6 mm between the ring and the separate measuring head, it can accommodate large shaft run- out as well as high levels of shock and vibration.

The construction of the ring, which is supplied in sections that are precision clamped around the shaft, facilitates 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. With both assembly methods performed in-situ, there is no need for complex assembly and the ClampFit method particularly suits retrofitting precision speed control on existing machinery.
