1 AMO GmbH PRODUCT OVERVIEW Ocber 2017

2 The company The company AMO GmbH was founded in 1994 develop and manufacture encoders based on an inductive scanning principle. Since that time inductive angle and linear encoders were developed and manufactured. AMO GmbH is continuously improving the inductive scanning principle and expanding the product range. AMO encoders are used in a wide range of applications as for example in the machine ol industry, aumation and in medical industry. To fullfill the highest quality standards and provide excellent service our cusmer AMO is certified according the quality management system DIN EN ISO 9001:2008. This quality management system supports us also in the further development of our products and internal standards. 2

3 AMOSIN - Measuring principle The AMOSIN encoders function on a patented purely inductive principle. The measuring scale is a stainless-steel tape on which a high precise periodical graduation of variable reluctance has been etched using pho-lithographic techniques. A coil structure, with a number of coils aligned in the direction of measurement, is implemented on a substrate using micro-multi-layer technology.

MASSVERKÖRPERUNG MESAURING SCAE Absolutcodierte Teilung Absolut Grating Inkremental Teilung Incremental Grating The relative angular movement in the direction of measurement between the sensor structure (in the scanning ) and the measuring scale periodically changes the mutual inductance of the individual coils, generating two sinusoidal signals with a 90 phase difference. The extremely accurate signal, and its immunity environmental influences, has the effect that, after conditioning of the signal in the evaluation electronics deviations of no more than 0.1% from the ideal sinusoidal form (harmonic content) remains. This allows high interpolation facrs be carried out in the course of signal digitisation. This can either be done in the encoder itself, or in the subsequent electronics (CNC etc.). With the incremental measuring method the graduation consists of a periodic grating structure. The position information is obtained by counting the induvidial increments from some point of origin. Sinca an absolute reference is required a certain postition, the scales are provided with an additional track that bears a reference mark. The absolute position on the scale, established by the reference mark, is gated with exactly one signal period. With the absolute measuring method, the position value is available from the encoder immediately upon swith-on and can be called at any time by the subsequent electronics. There is no need move the axis find the reference position. The absolute position information is read from the scale graduation, which is formed from a absolute code structure. A separate incremental track is interpolated for the position value. 3

4 AMOSIN - angle encoders AMOSIN angle encoders can be applied a wide range of applications due the pure inductive scanning principle and the robust IP 67 rating. Almost any diameter from about 80 mm up several meters can be manufactured based on cusmer needs. AMO encoders can be supplied for not only high speed applications for spindles but also for high accurate rotary tables and swivelling axes.... easy integration, for almost every diameter! Powerful machining spindles and direct drives can use AMOSIN encoders in purely a rotary velocity operating mode as well as in an interpolated mode for multiple axis machining. The extremly high resistance against environmental contamination combined with the protection class IP67 allows the use of the encoders for example close the bearings achieve maximum positioning accuracy. A stable press-fit mounted measuring ring provides a solution for a flexible design and allows a wide range of ring scale diameters. Adding a ring scale a rotating shaft or spindle offers compact integration of the inductive angle encoder, leading stiffer and space-saving designs, with lower masses and therefore lower moments of inertia.... have brains, for highest accuracy! The double scanning system in combination with the evaluation electronics MHS or MHSA achieves very hight accuracy on rotary axis. Accuracy errors related mechanical installation, disc eccentricity and bearing run-out are eleminated. The absolute accuracy is two times higher compared a single scanning solution. The integration of the AMO non-contact encoder ring scale directly on the rotating part, very close the bearing and without a mechanical coupling is the best solution for precision positioning and high accuracy. The mechanical flexibility of the AMOSIN angle encoders permits designers simplify and improve the integration of a rotary measuring system. Requirements regarding design, signal quality, reliability and robustness are met with AMOSIN angle encoders. 4

5 AMOSIN - linear encoders Open, and guided inductive linear encoders with incremental and absolute interface types are available for almost any measuring length. The AMOSIN linear encoder can be used in an exceptionally wide range of applications from precision measurement instruments, the harshest applications in machine ols, where robustness along with precision is required.... on the one hand small and dynamic! Miniature scanning s with a narrow 10mm wide, measuring tape make integration in spacelimited applications easy. The lightweight and high resolution of the linear encoder system meet the demands in terms of precision and servo control performance that is required when used in conjunction with direct drives. The purely inductive scanning allows a high protection class IP67 where the operation of the system is not affected by contamination and pollutants like dust, smoke or liquids. Particular noteworthy is the insensitivity against magnetic interference as there are no magnetic components in the purely inductive scanning principle.... on the other hand robust and precise! Applications often placing the highest demand on the precision and reliability of measuring systems. Machine precision, in the range of micrometers, is hard achieve in the very dirty environment found in machine ol operation. In particular, our guided, encapsulated inductive length measuring systems satisfy exactly these demands, even when the length be measured is extremely long. 5
