Technical data
Incremental encoder
Widely available from low pulse to high resolution pulse. A desired division pulse number is easily available because of internal manufacturing.
Outside diameters are available in series from ultra-small type to large type and selection should be made in accordance with the fitting shaft and division pulse number.
All products are of thin type, and especially the hole type is an encoder best suited for fitting.
Investigation is possible under optimum conditions such as noise resistance and reduction in current consumption depending on the purpose of use.

■ Precautions in assembling the hole-type encoder
Eﬀect on encoder of thrust load

Eﬀect on encoder of radial loadAbsorption of axial fluctuation of flat flange is within 0.15mm

Basically it is difficult to absorb the radial load becauseof the flat plate.
Radial eccentricity should be less than 20 micron.
