RotoLine 4 Product Overview Rotary encoders: Precise measuring technology with defined values SIKO has united the rotary encoder range under the name of RotoLine. There are the following three product categories, depending on the measuring principle employed in their typical applications:Magnetic rotary encoders â–  â–  Optical rotary encoders â–  Geared potentiometers The comprehensive SIKO product know-how permits a wide selection of types ranging from inexpensive rotary encod- ers in miniature format with simpler me- chanical designs to sophisticated, high resolution products – in housings made of plastic or tough die-cast aluminum. SIKO rotary encoders are essential for tracking lengths, angles and speed in machines and systems. With a host of dierent designs and customized ap- plication specifications, rotary encoders serve as the basis for robust measuring processes for a wide range of dierent mechanical engineering applications. Mounted on a shaft or spindle, they track measured values as incremental or abso- lute signals. The measuring principle can either be optical, magnetic or based on an electrical resistance (geared poten- tiometer). The information obtained is then available for higher-level control- lers or direct display on indicators (refer to catalog 6 DisplayLine). Magnetic rotary encoders Magnetic or optical measurement? Under extreme industrial conditions the mag- netic SIKO rotary encoders ensure par- ticularly error-safe measurement.The reason: On magnetic rotary encoders, a sensor tracks the number of north- south poles of a magnetic ring mounted directly on the hollow or solid shaft. As the measurement principle is based on the alternating pole forces of magnetism and is therefore not dependent on an unobstructed line of vision or system cleanliness, these rotary encoders are particularly suitable for applications in which optical length, angle and speed measurement can produce faulty results. . . 12 2 . 22
Reliability and precision are redefined, because this SIKO development makes use of the fascinating advantages of a technology with its resolution, scanning reliability and robustness that opens up completely new applications for these compact measuring systems reaching far beyond those of optical rotary encoders. . 32 . 42 . 52
